Digital Projector Give A Bigger Picture

Digital Projector  Give A Bigger PictureDigital projectors are those video projectors which are used in conferences for presentations. The digital projectors receive video signals from, usually, desktop computers and display images on large screens which can be easily comprehended by all in the gathering.Two Types of Digital ProjectorsTo begin with, there are two technologies used by "digital projector" s, the older one being the LCD, liquid crystal display with independent transparent panels of LCD for each constituent primary color (red, blue and green.) The image transmission depends on the signal received by the projector from PC which redirects the light signals through these LCD panels and lens onto a screen. The LCD projectors look pretty similar to older slide projectors and are simple in construction and thus cost less in comparison to their successors DLP projectors. The LCD can be thought of as slides placed at the focal length of the lens making it complete. Clarity of picture in LCD projectors depends on the number of pixels it is set for. (Pixels are smallest area of data or picture holders)DLP Projectors: The Latest of the Digital ProjectorsDigital Light Processing or DLP is a technology developed by Texas Instruments in 1987. DLP projectors bring in a paradigm difference in technology in image projection to board rooms. Unlike their predecessors, DLP projectors make use of tiny mirrors or micro mirrors to reflect light images to pass through the projector lens and onto a screen. Each mirror can be thought of as representing a pixel. The mirrors reflect primary colors in rapidly rotating succession as actuated by a rotating color filter wheel. The image of rapidly changing colors constructs images for human eye perception. The micro mirrors are collectively called as DMD or digital micromirror device.For the sake of enhancing picture clarity, the rotating wheel is provided with a plain patch which allows plain white light. This type of DMD projectors are also known as single chip projectors. The three chip projectors are a bit complicated but offer better clarity. Here a prism splits the light from lamp into primary colors which are redirected to DMD which recombines them before projecting through the lens.Where Is the DifferenceDLP projectors are lighter and give far better pictures. Single chip resolves 16.7 colors while the three chip model does a, hold your breath, 35 trillion colors.Commercial ModelsTexas Instruments is the pioneer who owns the patent for DLP technology. Fraunhofer Institute of Dresden of Germany developed the same technology simultaneously and markets it as Spatial Light Modulators. HP, Samsung are other market leaders in both LCD and DLP technologies.

CD/DVD Burning on your Personal Computer

CD/DVD Burning on your Personal Computer

Recently CDs and DVDs have become very cheap, both in respect to the disposable media and the burning hardware. Buying a CD or DVD burner has become an affordable solution to making back-ups and a lot more.CD media and burners have been around for a very long time. They have become very affordable for many. CDs have a capacity of 750mb and re-writable ones can be bought. CD burners have dropped dramatically in price. So much so that they have become an absolute standard for any new computer. Some computers have multiple CD burners to make burning multiple copies of data a lot easier.DVD media and burners were released a while after CDs. They cost more than CDs but also offer better features such as 4.7gb of storage space and compatibility with DVD players. DVD burners and media cost more than CDs but the price gap is slowly closing. Most new computer will have DVD burners or at the very least DVD readers.Using removable media for task such as back-ups, movies or music has become very popular with consumers. Its simple, can be taken anywhere and is very affordable. In the case of back-ups its a viable solution to making off-site back-ups of important data and documents.These two technologies have become a part of everyones lives but may soon become obsolete. In the near future different technology standards will be released. Sony is set to release the blu-ray technology thats set to change the way we exchange data. It will have at least double the storage space of DVDs and products such as the Playstation will incorporate this new standard.The second is HD-DVD. This stands for High Definition DVD. This will have an even sharper image than the current DVDs and will also have a lot more storage space. Deciding when to embrace these new technologies will be up-to the consumers.

Printing Glossary And Terminology

Printing Glossary And Terminology

The following is by no means all of the terms that you may come across when dealing with your printer. What we wanted to do here is provide you with many of the most common terms so you can understand the catalog printing process better. Many of these terms are ones that you will not have to deal with at all as most catalog printers offer full service.Bleeds: This is where your design calls for the ink to go all the way to an edge of the page. To determine the number of bleeds you have to count all of the edges the ink goes to. In other words, your page has a top, a bottom, a right, and a left edge. Each edge your ink will go to is one bleed.Bluelines: This is a proof of your catalog on film that is used to verify that everything is correct.Camera Ready Art: This are not your photographs. Those will be photographed as half tones. (See glossary term, Half Tones) This is about your artwork. It has to be provided to the printer on a board or paper ready to be photographed. If there is more than one color, each color has to be on a different sheet of paper or board piece. You should also include the composite where all of the colors are on one paper or board so the printer knows what the outcome should look like.Color Key: This is an acetate film proof of your catalog. Each color is produced on a separate sheet, then laid over each other to make sure everything is in the right place. This method is generally less expensive than match print, but not as accurate. (See glossary term Match print.)Composed Film: These are pieces of film that are ready to be stripped or put together with other pieces of film to make plate ready film. Plate ready film is used to make the plates your printer will print your catalog with.Coverage Percentage: If your catalog has areas where there will be 100% ink coverage and you tell your printer, then they can use the correct press and processes to produce it for you.Cover Ink: There are two types of ink to choose from for your cover. CMYK and PMS. If you are selling an industrial product you might use PMS, but for most products the cover uses the CMYK method for processing images.Cover Stock: This is the heavier paper used for the cover of your catalog. It can also be used for the interior pages if you want to present your product better. High end products are usually sold in catalogs that use this higher quality paper throughout the catalog.Design: The combination of everything from your photos to your fonts, layout, logos, artwork, and all to produce a piece that is ready to photograph and print.Die Score or Cut: This is the method used to crease where your catalog will be folded. If your catalog has pockets this is the method your printer would use to score the crease where the folds are needed.Emboss: This is where the printer creates a die and stamps your paper from the rear to make a shape stand out. This can be raised print or a logo, etc.Foil Stamp: This is where your printer creates a die that is used to stamp metallic gold, silver, or other colored material onto your catalog pages or cover.Fold Type: Whether your catalog will be folded in half from top to bottom, folded left to right like a magazine, or tri-folded like a brochure.Half Tones: This is where the printer takes the photos you want in your catalog and scans them or shoots them with a camera that has a honeycomb lens. This converts your photograph to an image made up of many tiny dots that allow for correct printing of the photos.Match Print: For high end product catalogs, this is the recommended method. Each piece of film contains one of your colors, then they are laminated together to make a single piece ready for printing. If the accuracy of the colors is important to you, then this choice is best.Number of Pages: The number of pages you choose for your catalog. This is always in multiples of four.Output Film: To rip your digital files and produce your art as film that is ready for print.Output Ready Disk: This is a disk you provide to your printer as a complete product. The only thing they need to do is convert it from digital to analog film. The disk should contain a separate folder for images and one for fonts.Perfect Binding: This is a binding process normally used for high-end product catalogs or catalogs that will be over 80 pages.Perforate: If you want to have tear outs such as coupons, you would instruct your printer to perforate the edges of the tear out.Quantity: The number of catalogs you need to have printed. The larger the quantity, the less each catalog will cost to produce, so you may want to order a few more catalogs than you need. They can always be distributed elsewhere.Reflectives: This is where the printer makes a print from your photographs or your negatives.Saddle Stitch Binding: This is a binding process normally used for catalogs that will be less than 80 pages and to save money over the perfect binding method.Scans from Transparencies: Scanning is the process that takes your transparency and records your images as a digital file.Set Type: Laying out your type onto a page. This term also applies to the selection of the right font and typeface for your layout.Spread or Flat Size: This is the size of the paper that will be used to print your catalog on. Once folded it will become the Trim Size. See glossary terms for Trim Size.Text Ink: This is the type of ink and the number of colors you will choose for the interior pages of your catalog. The two types of inks you can choose from is CMYK and PMS. If you will be using photos, you will likely be going with CMYK. If everything is text and few images, your printer may suggest PMS.Text Stock Paper: This is the lighter paper your interior catalog pages might be printed on if you are trying to save money or you are selling an industrial or low end product.Trim Size Folded: This is the final size you want your catalog to be. For instance, if you want an 8 by 11 catalog, the printer uses 17 x 11 paper to print it, then folds it in half so it becomes 8 x 11. Trim Size Folded is the term the printer uses to ask you the final outcome size you desire. Always remember that the width is always given before the length or height.

Its Your CD Printing Guide!

Your CD is 1.2 mm thick disc of almost pure polycarbonate plastic, approximately weighing 16 grams. Often, your CDs carry aluminum layers that make their reflective surfaces, which are protected by lacquer films. Gold is but rarely used for data longevity, such as in some limited-edition audiophile CDs.Your CDs normally have directly printed lacquer films, not adhesive labels. The process of directly printing the lacquer films on CDs is often termed as cd printing. Usually, the lacquer films on CDs have ability to absorb ink and are printable. Normally, the methods used for "cd printing" are INKJET PRINTING, THERMAL TRANSFER PRINTING, SCREEN-PRINTING, and OFFSET PRINTING.INKJET cd printing uses CMYK Inkjet printers to put tiny droplets of liquid ink onto specially-coated CD surfaces. The CMYK Inkjet printers are usually automated robotic systems that load and deposit CDs automatically after some initial manual setups. The inkjet cd printing results are amazing in high resolution and vibrant colors. Inkjet cd printing is ideal for small runs with photographic quality print, or when you desperately need fast results. However, in Inkjet cd printing, your per unit prices do not drop, and thus you may find inkjet cd printing uneconomical as compared to silkscreen cd printing, or lithographic cd printing. THERMAL TRANSFER [*_*] is the process based on melting a coating of colored ribbon onto the surfaces of your CDs. The thermal transfer printers contain two ribbons one containing panels of cyan, magenta, yellow and black, and each color is printed individually onto the second ribbon- the transfer ribbon. This [*_*] is cost effective for small runs and offers you superb finishing superior even to lithographic [*_*]. Offering quick and excellent results, the thermal transfer [*_*] has grown very popular for small runs. SCREEN [*_*] a printmaking technique that creates a sharp-edged image using a stencil. SCREEN printing is also known as silkscreening, or serigraphy. The screen [*_*] is a cost-effective method for larger quantities of CDs. It is most effective with simple designs of few colors. The screen [*_*] offers fine finishing results in vivid colors. Your per unit cost becomes pretty frugal, when you order over 1000 units in screen [*_*]. OFFSET [*_*] is a widely used [*_*] technique where the inked image is transferred (or "offset") from a plate to a rubber blanket, then to the printing surface. It is often called Lithographic (Offset) [*_*], when used in combination with the lithographic process. This [*_*] has become the most common high-volume commercial printing technique nowadays. This [*_*] technique offers fine results in highly detailed photographic images. This is the perfect option if you need upwards of 1,000 units based on highly detailed artwork, producing a superior finish to silkscreen printing at a relatively comparable price.You can choose your [*_*] and [*_*] services, according to your need and requirement. You may find your [*_*] service at your local area, or you may hire your [*_*] service online. Of course, you can find lots of [*_*] services online, but you should choose the most favorable one.

Getting A Rack Mount Computer

Who says that only professionals need rack mount computers? This is a very erroneous assumption that many people have about "rack mount" computers.Anyone, including you who are confronted with the problem of how best to handle your computer, surely needs a rack mounted computer. One of the biggest mistakes people make is that they think they are far better off not buying one.The argument that only professionals need rack mounted computers certainly springs from the cost of acquiring one. But what should be clear is that if you can afford it, why not go for it instead of the normal computer. A smart person would take a rack mount computer over a regular computer any day of the week.You need a rack space for your computer. In other words, you need a rack mounted computer to ease your work with the computer, even if you are not a professional.Before going into details on why you need a rack mounted computer, it is necessary to familiarize ourselves with what a rack mounted computer really is. Many people are not very clear on exactly what it is.A rack mounted computer is simply computer that is mounted on a metal frame (other wise called a rack). To prevent use of inferior computer racks, the Electronics Industries Association (EIA) has provided standards for computer racks. This standard helps to ensure that you only get to use the best computer racks for your computer. Note that there is a big difference between a computer rack and a computer cabinet. The computer rack is the frame used for mounting the computer, while the computer cabinet is fitted with doors and usually side panels- and used to put in the computer.
