When it comes to CD & DVD printing, there are now so many choices that run contrary pressure (where size and cost are the main factors), you are facing the difficult choice of litho, screen, inkjet, digital and thermal print face on CDs and DVD's, or a combination of 2 or more of these.
How can you determine what is best for your run from CD or DVD 's?
As a basic guide, keep the following principles, solid colors grid should be printed asPantone should. CD & DVD look like a work of art, consisting of photos or CMYK mixes with many shades and nuances better offset printed or better still printed in the new generation of digital UV curable CD and DVD printer. One of the best examples of this new printing process is developing a new printer from Sun Chemical, the resolution, life imparts luster and color of the image an almost 3D feel discs to them.
Screen printing requires the graph to be dividedinto constituent colors. A film will be dropped from each of these colors (usually also a white base). Made from this film, an image that is a 12cm square with a mesh of porous area is not being printed as not yet well drained area. 1 color of ink is forced through the network with a rubber blade (as called a blade) on the surface of the disc. Screen printers can store up to 5 colors, applied one after the other. As soon as the ink was applied, the disc passed under a strongUV lamp which cures the ink to consolidate it. This method allows for some creativity, as not applying ink in some areas reveals the silver disc layer below, or enter through special coatings on certain areas of the disc, or, conversely, a high-gloss matte finish.
Offset printing starts with photographic imaging used to create records. In lithography (also known as a real offset printing 4 color printing) are formed, cyan, magenta, yellow and black (CMYK), which also usually aWhite base.Artwork is separated into these components and colors are made from the exposed film 4 plates. This ink is then projected onto these rubber rollers and select the color, applied new application to the surface of the disc. Once the 4 colors were then applied consecutively disc is hardened under a strong UV light.
Digital is the latest generation of disc printer uses UV curable inks and multiple print heads, the consumer inkjet are similar, but on a much larger scale. EachColor by 8 separate heads, dramatically increases the resolution and variable droplet size application allows a greater variation in the colors. A digital printer to be printed as 1200 slices per hour compared to a consumer inkjet-30's or so. Once the ink has a white base, it goes under UV light used to be in a hard, shiny surface and permanently cured.
Inkjet and thermal-offer an inexpensive solution for very small runs of full color printed CD & DVD, andthe lead time is usually within hours instead of days, although of course this depends on the size of the duplication plant.
Inkjet printers use the same technology in consumer printers found, using a modified Caddy on a disc to disc, and sometimes automated loading and unloading.
Heat (or thermal transfer) printing the image with a color film that is applied using a high-temperature process. This is a particularly expensive and inefficient way of printing discs, as itis a lot of waste film from the areas of the disc that is blank. There is also a very slow process.
Pantone solid colors and pressure should be avoided, either by inkjet or thermal as pantones will be difficult to play and solid colors will show banding or lines.
A professional photocopier will not only be able to offer one of these methods but especially in a position to advise on which of these methods is the best for your artwork.
