What is Max Length out of IPF 8300

[deanwork]

Using the Canon Photoshop Plug-in for CC, does anyone know the max length I can print from the Canon 8300?

I need to make some 30x80 inch prints but I"m curious how much longer I could go using the plug-in. It seems to me I remember someone saying 100 inches or so.

Way back with the iPF5000 I heard 50 ft. mentioned. Curious, I checked the plug-in "size options" dialog of my 17" 5100 and the max. is 708.66", or 59' and change, which should take care of most of your needs - maybe more in the 8300?!

I can't tell you what is the real limit, but Keith Cooper printed a huge panorama:

(check the last third of the article)

Good luck.

Plug-in file size limit of 60K pixels the article says. That is way lower than the Photoshop image size limits of 300K x 300K pixels. Maybe the PS image size limits do not even represent what can be printed through a normal driver. Not using both applications for printing so can not base it on experience.

Well my 30x80 print at 300 ppi comes to 2400 x 900 pixels. So hopefully the plug-in will work.

I believe Keith had to abandon the plug-in and also reduce the output to like 160 ppi or so.

John, on my lil' ol' 17" 5100, I created a gray doc. in PS of half the height and twice the height of yours @ 300ppi X 15x160" = 4500 x48,000, or 216MP total - same as your 9000 x 24,000 (you omitted a "0" in your calcs!).

I then created a 17 X165" custom page size in the plug-in to print it on. It digested the whole affair without a hiccough, starting printing normally sans error messages, and I aborted it after 6" or so.

I have no idea what Ernst was referencing with the supposed "60K" plug-in limit (?60MP), and his linked article has no relevance I could see. But of course even 60MP is ridiculously low for a LFP - about 22x30" @ 300ppi. (Edit: I see he was referring to Keith's article. Did he mean 60K MP, which would translate to 6000MP if math is correct.)

Have you tried just entering your parameters into the plug-in to see if they're accepted? I can't believe they wouldn't be...

I assumed 60k pixel length and at 300 PPI printer input that is still 200" but any other interpretation is welcome.

Yes I also assumed he meant 60K pixel limit in the longest dimension. That would be the only thing that makes sense. But who knows what the total file size or pixel count limit would be for both dimensions at a given file size.  Why can't Canon just tell us these things in their literature. None of these printers have good documentation for things like this. I'll bet even the service techs don't know.

If you have a document in Photoshop with a pixel dimension over 60, 000 on one side, (does not matter which side, and does not matter how short the other side is) the Canon iPF Plug-in in grayed out (unclickable) in the application menu, so you cannot even export to the Plug-in.

So this translates into a print length limitation of 100 inches @ 600ppi if you intend to send files at native resolution to the printer. The paper length can certainly well exceed that (for inclusion of blank borders).

Unless you are printing using "Plain Paper" as the media setting, all of the media settings for coated fine art media only allow for 600ppi input.

Or just do what Keith did and send at lower ppi input resolution and let the Plug-in do the resampling.

If you print from Photoshop then you will always be limited to what Photoshop allows, which may be nothing like what is possible.
Get a print programme and print from that. I use Mirage but there are many.

Photoshop's limit is 300,000 pixels, nowhere as little as the 60,000 maximum of the Canon Plug-in.

Well, if that's the case, it greatly exceeds John's requirement of 80" @ 300ppi - 24K pixls. There's no question in my mind that it will print through the plug-in. My 5100 didn't balk at the plug-in accepting, or beginning printing, a 160"/48K wide document with the same total pixel count as his.

There is no problem at all. I have made several prints 80 - 100 inches long @ 600ppi with no issues at all.

[deanwork]

Ok, good. Thanks for all the comments. That is what I thought. It is good that the plug-in tells you what will not be accepted by graying out the output tools in its driver.

For anything longer than 100 inches I would probably be using Q-Image like I do with the HP, but I'm so used to the Canon plug-in for the 8300 that I'll stick with it until I'm forced not to.

Just saw this - and the mention of my 14m print (571 inch)

The pixel limit was discovered the hard way with quite a bit of wasted paper, canvas and ink :-(

The actual size limit is a bit over 60k pixels, but that's now the limit I work to. The driver does some pretty good resampling, especially if you've down-sampled from a larger size.  It's also the only time I've specifically used the internal disk, to spool the job before starting printing. If it got to the printer's disk, then it seemed to work.

My queries to Canon went all the way up the chain, and it seemed that no-one knew for sure what the limits were and why. Whether it will be fixed with the next generation of Canon large format printers I don't know.

All the limitations seem to be related to re-using old bits of code, where no-one ever thought to make it handle really big numbers ;-)
Canon's drivers and software could do with a deep overhaul to bring them up to date with newer systems.
