As you are very likely aware, today the "plate making" (if a plate even is used, as such) is often done directly from digital files with no intermediary film steps. Even as I was typing the phrase, I was thinking "someone in the printing profession is going to complain about this", but I also decided I didn't wish to go into the detail...)." ------------------------ I don't mean to quibble about semantics and would let this subject go, except for the impression that you have left that printers can "sharpen" images in the platemaking process. I believe you are confusing two different concepts which use the same word. Image sharpening (aka USM) is the enhancement of apparent image sharpness by increasing edge contrast within the image. Plate sharpening, OTOH, refers to dots on one plate being "sharper" than dots on another plate and thus (usually) printing lighter. Typically, plates made by CTP processes are "sharper" than "conventional" plates made from imaged film. In order for the CTP plates to match the conventional plates, the mid-tone dot sizes are adjusted in the CTP plate-imaging RIP to give the same print densities as the film-based dots. This has nothing to do with image sharpening. Printers generally endeavor to duplicate the files they are given. If a printer has a long-standing relationship with a particular customer, the printer may "improve" furnished files by color-correcting or enhancing sharpness. Absent other instructions, the printer is generally going to give the customer just what is in the files. The files should be properly sharpened before submission to the printer. I'm not a pressman (and despise the nickname "Press"<G>). I have owned a very nice printing company, including an Indigo press, but that is another story.
