It is all about the screens. Well, who cares about screens? If you buy offset color printing services you have to know the differences involving the 2 different screen technologies used in commercial printing. It affects the quality of your entire color printing. You could possibly know several of this stuff, but a majority of people who buy printing do not know what will you learn on this page. This is a little technical, but stay with it as you might want to commit to changing in the manner your printing is printed. Why don’t we start.
This is one way it truely does work. Your files visit pre-press where they may be reviewed for technical errors before being converted to screens for printing; oahu is the 1st step in the act. Customer files go to some plate maker being processed and then transferred (offset) to 4 different metal plates, one every one of cyan, magenta, black and yellow. Each plate transfers some of it to some rubber blanket as well as the blanket offsets some of it to the paper.
Most commercial printers use conventional AM (amplitude modulated) line screens, that are dots arranged in the rosette pattern to makes images. Meaning each screens plate must align perfectly at very high-speeds of rotations in the press cylinder to keep registration sharp. At typical press run speed alignment in the plates can be unstable. The actual way it works is a few dots are large and several dots are small depending on their tonal value. The greater the dots the more ink they pick-up.
The most widely used line screen dots are from 150 to 300 dots per inch with respect to the screens employed by the printing firm. Printing companies choose a type of screen and use it for all their printing, so that you can’t ask your printer to utilize high dot line screens. An issue is conventional screens use a lot of ink that pools together. Detail is reduced a result of flooding the paper with an excessive amount of ink. Color gamut is the variety of colors that may be printed. Excessive ink inhibits subtle colors and tones are lost as the color gamut is reduced. Subtle colors can not be printed and moire patterns can occur in textures and patterns. Something is banding in color gradations because it is tough to print smooth transitions of color tones with AM screens.
As with any print buyers you want your advertising, sales, marketing promotions to be impressive and attract a lot of attention cheaply. You may be surprised to understand how the cost and turn-around times using FM screening technology is probably you can forget and might be less cash then what you are paying for conventional AM screen printing.
Next time your ready order printing in color ask your company what line screen they will use and when they’ll use stochastic screens. Don’t be surprised should they never heard about it. Should they can’t you should buy good quality printing by getting a company which uses high-definition FM stochastic printing screen technology. When excellence can be obtained good is just not enough.
