All About Process Printing

Among the number of printing techniques one of the most popular printing techniques is that of the process printing, which is widely used throughout the world. The name process printing has been derived by the short form of the four color printing process, which is used as a reference to the way in which the images are prepared for the press. Process printing was invented in the early twentieth century and it was developed along with the offset printing, however it overtook the other printing methods in popularity by 1950's. It is a very cheap, rapid and efficient method of printing and yet yields amazing images in mass production. A majority of the printing objects which we enjoy these days are prepared using the technique of process printing. The glossy magazines, mailers, brochures, and the various other color printing projects are all developed using this innovative technique of printing. It so happens that in some cases the process printing is combined with some different colors wherein the different types of inks are mixed to create some specific color choices. Spot colors are essential for metallic inks and some special colored projects. In order to prepare an image for process printing, the image is separated using four different color components cyan, magenta, yellow and black. This process of color separation is referred to as color screening and this is usually done digitally. For each of the four different colors some separate print plates are prepared for each of the four colors. Each color is segregated by a series of tiny dots which implies that in the areas where the color is sparsely sprayed, the tiny dots are small and they are spaced well apart from each other. On the other hand in the different areas where the color is densely located the dots are big and they do not possess any space between them.Each of the different colored plate is printed separately and then it is laid on top of the previously printed ink. As all the four images are printed, the outcome which is produced is that of a colored image. The tiny dots which are present on each of the plates will come and merge together thus forming a colored image, however these dots can be viewed with the aid of a magnifying glass. It is quite important that the plates are well aligned with each other incase they are not done then the result which is obtained is blurry image. This technique is an excellent printing technique, which allows the printers to efficiently produce colored images. Michael Jordan is a Copywriter of Alabama printing services
