And after that, having it produce a print sized as you 'specified'. So based on what you report, while Jane and the article are obviously correct, the issue is handing something to the imagesetting that will not pop an error. It may not need an actual document with 2400 pixels per inch yet, you describe that without this, it either doesn't print the size correctly or just takes a dump. You can send the print driver an image as low as 180PPI but ideally a bit more** and it does indeed produce 1440 (or 2880) dots per inch.īut this imagesetter may be a very different beast. Its output resoution is 1440 or 2880 DPI but you would NEVER create a document with that actual, physical pixels. Take an Epson desktop printer as an example. Jane is correct but then I suspected the imagesetter might fail without having the actual document set (far too high) and apparenly it did. We are not going to spend the money on a new RIP, we will outsource the long runs.and a guy loses his job. A person will lose their job if I can't figure this out. I'm thinking this is happening when opening the PDF and it changes to 13.33 x 13.33. The result is a 2400 dpi tiff, the size is correct as 13.33 x 18.86. I then change the image mode to bit mapped. So after opening, I change the canvas size to 13.33 x 18.86. No matter what I do it make sit square.įine. When two or more images are included in one PDF file, then the resolution of these images must be the same dpi: if one image is 300 dpi, then another image cannot be 72 dpi Yes / No. Even though in the PDF I changed every page box to 13.33 x 18.86. When we talk about the resolution in PDF, we are talking about the dpi of the included images Yes / No. I open the PDF in photoshop, no matter what I do it changes the canvas size to 13.33 x 13.33. (Must be 2400 or platesetter will reject) (It MUST stay that size.)Īnd the PDF is 2400 dpi. Original file is a PDF of a black only PDF. I can't get the images to stop reducing slightly.
ADOBE FIND DPI OF PDF HOW TO
Our imagesetter requires 2400 dpi one bit tiffs to burn a plate.Īfter a lot of messing around I have finally figured out how to do the above, and make a 1 bit tif the platesetter will accept. Background: We have lost our RIP server, we don't print a lot of long run envelopes anymore.
