Staff Gabe Posted October 15, 2020 Staff Share Posted October 15, 2020 It seems to be that specific gradient. Try dragging out a new gradient and you should be fine Issue logged. Quote Link to comment Share on other sites More sharing options...

Staff Gabe Posted October 16, 2020 Staff Share Posted October 16, 2020 That's because PDF tries to honour gradients without being rasterised, whereas jpeg is a raster format. Quote Link to comment Share on other sites More sharing options...

Thanks for your explanation, for me still stranger, as PDF common use in offset printing, if PDF change the color I could not imagine to many complain will be received the designer. I have attached the afpub file with change the color and still implement the gradient @same spot with Color Cast was Occurred, and now the color didn't missed it.

HANDJOJO Posted October 16, 2020 Author Share Posted October 16, 2020 Dear All/Gabe, Here I send again a sample two sample of PDF: 1. Export as a PDF File 2. Direct Print as a PDF File I send a long with the Screenshot of each setting during export and direct print the document preset : * Color Format: CMYK/8 * Color Profile: U.S Web Coated (SWOP)V2 I also attached the *afpub file for investigation. As see the Direct Print as a PDF the color more bright (similar to RGB Color) compare to Export as PDF (PDF/X-4), both color profile same as the document color format: CMYK/8. Please help & Advise. Look forward to receiving the reply. Thanks & B/regards, The Result Direct Print as PDF The Result Export as PDF Setting during Export to PDF Setting during Direct Print as PDF Result Direct Print as PDF.pdf Result Export as PDF.pdf Translucent_Color_2.afpub Quote Link to comment Share on other sites More sharing options...
Staff Gabe Posted October 22, 2020 Staff Share Posted October 22, 2020 You see this difference because the print drivers use an RGB printing model. When you Print to PDF, you end up with a RGB pdf. When you Export a PDF, you end up with the colour profile you of your choice (if supported by the pdf model you select). Why don't you use the dedicated PDF Export option, and not the Print to PDF. You have 0 control over what comes out of Print to PDF. Quote Link to comment Share on other sites More sharing options...

Dear Gabe, Thanks for your advice, what is the reason I used the Direct Print as PDF, that I have the document to be print as facing pages, if I use export to PDF the PDF document for 1'st & last page as independent page not as facing page even I have create the document to be facing page, if I'm not wrong in Print Menu there are menu how to control the Color Handling: whether by Printer or Performance by Application under Color Management, the sample I have been share is Direct Print as PDF & Export as PDF (the result should be same, cause for both use the same Color Format & Color Profile). Sorry I send the sample again what the reason I use the Print as PDF as per attached. *Export as PDF Print Ready* *Print as PDF* Above is the sample between Export as PDF and Print as PDF Thanks & B/regards, Quote Link to comment Share on other sites More sharing options...
Staff Gabe Posted October 23, 2020 Staff Share Posted October 23, 2020 If you need your Pdf to start on the left, just set this in the Document Setup > Start on > Left Quote Link to comment Share on other sites More sharing options...
