HI There. I have read through forum posts first before posting but find the conversations a bit confusing.
What is the difference between
PDF Prepress. Pdf.X1A. PDF X-3? . Under the Colour settings - what is the difference between output colours as cmyk and native?
I find that when I create pdf x1a and pdf prepress cmyk the colours are different from pdf prepress native. My documents are created in cmyk.
I also experienced that greyscale images became quite a bit lighter in X1a native
I do design work for litho printing. I was told by my printshop to use pdf prepress native, and not to embed colour profiles.They say pdf x1a is not a good way of supplying pdf for print. I will supply my printshop pdfs as they request, but the question is when Im sending files to other printers - do I do it the same way? My concern is how do it affect my document if I don't embed colour profiles? Many times I am not in communication with the printers as I supply artwork to clients who then choose to have their artwork printed from their own printing company.
I was also told by two companies not to use any compression, but that results in huge file sizes. The default setting is zip compression, can that create problems at the printing companies that receive the pdf's?
