I am a children's book designer writer. I am trying to format my first picture book for printing. I have worked the images in RGB, but thought I should convert in Affinity before sending to printing. I sent of for test print in RGB and they are super bright. I realize that was a photobook and won't be the same quality as printed for publishing.
First, am I correct in this thinking or should I leave it in RGB and send to printer that way?
Export gives so many color options and I am not familiar with them. Should I export in RGB 8, 16, or 32...or CYMK in sheetfed coated or web coated or those options in uncoated?
Also, what format is best? I've been using PNG for export.
Thanks in advance!
