I’m trying to print (selection) a tiff image at 300 dots per inch but the resulting image keeps coming out at 72 dpi. Please fix this !

What is the workflow you are actually doing? What are you trying to print, and from what? Which print dialog? Is it even in Rhino? Seriously, you’re not being clear.

I just checked Ver.6 (Yes WIP, I understand) It also is not writing the correct dpi to the EXIF data while creating a *.tif image file…

I filed the issue as RH-41060 . [image] stevebaer: We actually don’t write any exif data to our image files so Windows is just making up a default number. What application are you using to print the image? @stevebaer , we actually do write that information. See the YT issue for information. /…

[image] Cayenne: Rhino is not printing correctly because of the discrepancy between the print dialog dpi and the actual dpi that is recorded to the EXIF data in the image Spot on!

But what print dialog dpi is being referred to? The Print command for linework has nothing to do with renders, and the Print function in the render window is some bog-basic tool that has no settings, it’s all up to the printer driver. So where exactly is “Rhino” not “printing” renders at the “right”…

Screen shots are above…If I tell my printer to print this at 100% it will come out at 83" x 83" not the 20 x 20 I specified, and I don’t want to calculate in my head the proper reduction percentage. if this worked the way it should it would come out the printer at proper size with NO post processing…

So… I think what is happening is this: He prints his viewports directly to tiff-format, specifying desired print size and dpi. This results in a given dimensions in pixels (3800x2400 or similar). He then copies this file to a thumb drive, which is inserted directly into a printer. The file is then…

“without a media size being specified, based only on pixel dimensions and dpi (ppi, rather)” <-----Yes, kinda, I tell the printer !00% it then sees the the incorrect 72 dpi/ppi within the exif data of the image and the print size is way large! The Resolution pull down menu in the print dialog has n…

entering a custom dpi has no effect it is always 72
