Photoshop 2019 issues

First of all there's the issue of Photoshop resizing PDF files to a completely different size than the pdf is... This you should be able to fix by resizing the page. Reported on this forum back in december 2018.

Second huge issue is the fact that if you open a large pdf file in photoshop you can not save it back to a pdf file. This is no good as we sometimes have issues with pdf files that we have solved by simply opening the pdf in Photoshop at 600 dpi and then save as a Photoshop PDF. This worked fine in previous versions of Photoshop...

Third, apparently you are not able to save images larger than 4Gb as TIFF files... If your image is larger than 4Gb you have to select a different file format.

I opened up my pdf (1185x1750 mm) at 300 dpi and saved it as a JPEG. I placed the JPEG in an InDesign document and exported a new pdf thinking I'd be good. However, much to my surprise, the image is now compressed at the top of my pdf, covering just 1/3 of the document.

Fortunately I found a computer which still had Photoshop 2018 installed, where I could open the pdf and then save it as a Photoshop PDF, which solved the problem I had with this particular job.

    That is not a Photoshop limitation but a limitation of the standard TIFF specification. There is a specification for BigTIFF but it is not widely adopted.

    If you have a Creative Cloud subscription you can have both Photoshop CC2019 and CC2018 installed on the same computer.

    If you're producing artwork for a large poster, that's viewed from a distance, you don't need such high resolution – have a word with your printers, they may suggest something between 50 to 100PPI.

    Don't create a PDF from your Photoshop file for use in InDesign, instead Place the native PSD file into InDesign (and work in the RGB color Mode).

    If you haven't been given a spec from your poster printer, export the document from InDesign using the Adobe PDF Presets and select PDF/X-4, tick Crop Marks and Use Document Bleed Settings.

    Hi Derek.

    I work in the prepress department at a print shop and sometimes the pdf files we recieve from our customers can not be ripped for some reason, which is why as a last resort we open the pdf files in Photoshop. Most of the time the customers has nu clue as to why there could be a problem as the incompetence among people who create pdf files has grown exponentially every year since the desktop revolution... :-)

    The reason we use 300 dpi in these cases in to try to preserve the quality of the text. Preferably I'd like to use 600 dpi.

    If the text is added in InDesign you don't have to worry about resolution.
