Question: I used ps to make a book about introducing company products (that is, arranging some pictures and text), the parameters are as follows: A4 paper size (21cm * 29.7cm), CMYK 8-bit color, 300dpi, color profile: Japan color 2001 coated Does this meet the printing requirements (those in the printing house say they want them to be filmed)? Do you want JPEG or other formats after making it?
Answer: CMYK 8-bit color means that each channel is 8-bit, and CMYK has four channels, which together form a true color document. The film is actually a film. The film used for printing is generally four-color printing, so each channel ( Cyan, Pin, Yellow, Black) one film each.
It can be made into PSD or saved as TIFF, but JPG is not suitable. JPG is most suitable for network transmission and computer browsing, not suitable for printing.
