Find and Fix Errors

With the onset of the computer age, finding a way to use printers more accurately has become the task of those who want to get clear and perfect, or as near perfect as possible, images in print but with clean outlines to them. image setter (computer output device) and screen plate setters (raster image processor) are two of those systems that allow images to be produced cleanly.

With the computer output device, the purpose is to expose rolls of film onto bromide paper to capture whatever is there. This produces an exceptional quality black and white image to be used for all kinds of printing work. The range of width normally falls in the one foot to 44 inch range but the resolution is is very sharp and clear.

This machine has been overtaken by the raster image processor in the very recent past. The raster image processor produces a lithographic style plate which can be used with an offset printer.

All these forms of producing lithographic plates are for the purpose of printing multiple copies of a certain image or layout. This occurs in the printing and reproduction processes for magazines and the like and is how we get newspapers with colored photos etc. Before the plates go off to be put on the printing press, they are checked over for errors or mistakes and this is a much cleaner and neater way for doing this process as compared to long ago when each page would literally be stamped out with a last that was made up of hand mounted letters. This is what compositors did but is a little old fashioned now.

There is a long procedure involved in any kind of printing to make sure that all the copy is accurate and that the photographs being used reproduce cleanly. Below are some of the terms used in the printing industry with some idea of just of what the different terms stand for.

Copy editing is another way to make sure that all the news stories, or information that is about to be published, is confirmed and that images match up with the printed word. This is done well before the proof readers get to work and is just one of the multiple cross checks done before printing begins.

Proof readers check out a facsimile of the finished product before it is mass produced to stop any mistakes getting through to the public. Proofing, on the other hand means that someone makes up an accurate copy of what the finished product will look like before it is read through again to weed out any errors.

Of course, there are many other processes that take place just to get out, for example, a weekly or monthly magazine. Colored photos have to have a separate plate for each and every color that may be necessary to make the photo look natural. This is why color leaflets or pamphlets turn out to be highly priced. But by doing this, the image turns out crisper and cleaner than computer generated prints which are not clear at all.

For those who want to stay with the older form of printing, there are some companies that still use the old methods for that genuine look. However, cutting edge technology means that new innovations in the print industry are getting cheaper by the day.
