Title: Files > 50,000 pixels long?
Post by: Larry8901 on September 23, 2010, 02:10:03 AM
I am trying to print an extremely large image on an Epson 11880. The dimensions are no problem (64" x 530") and I can print the job as long as the total pixel length of the file is less than 50,000. Is this a specification limitation of Qimage? I tried various searchs and did not come up with anything. I would rather not downscale the image if possible. I am running Studio on Windows 7.

Thanks for the help.
Larry

What are the total pixel dimensions?  50,000 x what?  It's possible that you are just running out of Windows RAM.

Hi Larry,
There is no limitation on pixels as such but there will be a limitation on file size caused by your Windows system.
By my reckoning, your image is 302 M pixels and therefore (x3 for RGB) 906 MB.
If your go to Help, click Analize Current settings with the shift Key held down, you will be told what your system can handle with Qimage. You should be ok. with a modern system and W7.

Edit: Mike is on the job now so he'll sort you out if I'm wrong  ::)

Hi Larry,

If you go to the epson FAQ page you will find the limit is 30,000 pixels for mac etc. further down it says
Quote
The maximum printable page length is 590.55 inches when using the Epson printer driver. Using a RIP may allow you to exceed this limit.

Now from that, it seems you may have picked up some erroneous information, or maybe epson got it wrong.

If you set up your paging/swap file whatever, you will get it to print from qimage OK  :), (but if you can't, it ain't my fault ::) )

Best wishes, Ray

There is no limit (or very very large) using Qimage: you use the driver Banner Mode and the Qimage Poster feature to make very long prints that exceed the driver limit.
See Qimage Help, Learn By Example 6a.

The criterion is as I described in reply #2; I don't believe the paging file has any influence on this, I can make my paging file huge but the numbers given from Qimage Help remain the same.

Sorry for the late response and thanks for the feedback. The originating image is 54,000 x 10,800 pixels (8bit), saved out as a tiff  (PSBs are not recognized). I get a read error at the thumbnail stage unless I reduce the size to < 50,000. My guess at this point is it is Windows 7 32 bit limitation. The length is not an issue. qImage handles that as a single beautifully. I will try on an x64 system with more RAM.

The EPSON FAQ is old in relation to 30,000 pixels. That used to be a limitation coming out of Photoshop. I believe CS3. Since it has increased to 100K.

Thanks Again
Larry
