Hi
Is it possible to use Qimage to prepare an image for printing at another location?  Resizing, output sharpening, etc. then send the file to the printer in another town to print through his own software.
I have Qimage Ultimate (latest version)from when I had my own printer.  It seems Qimage expects to have a printer on-site.

That's what print-to-file is for.  You can drop down "Printer" and select "Print to File" on the bottom of the list.  The alternate way is to select "File", "Print To" and select "File".

Once you do that, you'll be prompted for the paper size, resolution, and the color space (profile).  Then you just use Qimage as normal: after arranging prints like you normally would in the live view, when you click the print button, it will print each page to file(s) instead of a printer.

H Mike
Thanks for that.  Do I need any printer-specific information from the printer?

Does the printer need to do anything else on his end, or just select the file and Print?

Sorry, but neither of us has ever done this before and I am having several very large prints made on canvas and don't want to make any big mistakes.

Thanks

You should ask the store or business that will print for you what color space he prefers. (profile)
He might say RGB or Adobe RGB or something else.
If you look at the screen snap, you see where you can accommodate his request  in the COLOR SPACE line.

There is also a red "V" for video which might help located on that same screen.
It is a tad old in so far as the buttons are different, but the information is solid.
I access Print to file with a Right Click on the Properties button on the right side of the printer and settings tab.
Mike will be later to fill in what I might have missed.

I see no one else has any comments.

I have reviewed Qimage "Print to file" and printing to canvas and understand most of it and tried the settings with an image.  I set the print size, the mirrored edge and back wrap, sharpening - no problems and will get the icc profile for the printer/canvas/ink combo. 

When printing to canvas, the canvas is on a roll, so only width of paper applies - I think.  So how does the page dimensions and placement of the image on the page in Qimage relate to the canvas width and the image placement on the canvas?  I don't understand what page dimensions and orientation I should use for Print to File for ultimate printing on a roll of canvas (say 44" wide).

I'm also a little confused regarding the portrait and landscape settings.   Sometimes when I switch these settings, the page orientation changes and other times, the image orientation changes, but I can't seem to get the image oriented on the page the way I think should be used for printing to a canvas roll.  Does this matter when printing to file, or is this done when actually printing?

If you are not designing full pages and you want to send individual prints, just check the "RIP individual prints" option when you print (after clicking the print button).  That will make a file for each individual print which is what you want if printing on roll paper and it won't matter what size page you use when laying them out as long as the page is big enough to fit the prints.

Hi Mike

Thanks for the reply.

Does this apply to "Print to File", which is what I'm doing rather than printing directly myself.

Hi Mike

I tried what you suggested and I don't see "RIP individual prints" option.

I printed the image to file and had a look at it.  Everything looks OK but the whole page is included instead of just the image.

Cheers

It's there every time you click the print button: and it only appears when you are in print to file mode.  See attached.

OK, I found it and it works - only the image with wrapping shows now, the rest of the page is gone.

Thanks again Mike

Cheers

Two questions:

1. My original tif file is 16 bits, but after I print to file it ends up as an 8 bit file - why?

2. After I print to file, a solid black line is on the bottom and right side of the image - at the edge of the actual image itself as if this was a fold mark and I can't seem to get rid of it with the different fold and crop settings.

Thanks

1: All output is 8 bits/channel.  That is driven by the fact that there is no such thing as a 16 bit Windows printer driver.  Qimage simulates 16 bits/channel using 8 bits so you will not be able to tell the difference visually.

2: That line is in your original image.  Zoom in and look at the original and you will see it.

Hi Mike

Thanks for the reply. 

I checked and the line isn't in the original image.  Also, now when I bring the image into Qimage, it looks all strange (looks fine in Affinity Photo) and the print size isn't working correctly now.   Do you think Qimage has become corrupted?
Should I remove Qimage and download another copy?

Cheers

Hi again Mike

I downloaded the new version and the problem I mentioned in my last post remains - it also kept all my previous settings.  I seems to have corrupted my thumbnail as well.

Next step tried- (again, this is printing to file for canvas)

I deleted the tif file and regenerated it.   The strange appearance (looked like a sand pattern) was gone, but adding canvas borders, folds and crop marks resulted in that line again - it looks like a solid fold line at top and right side of the image proper.  When I printed to file, it created 3 copies then Qimage froze.

Any suggestions for what to try next?

Thanks
Larry
