Title: Contact sheet printing
Post by: picstart on June 01, 2009, 10:32:19 AM
we are trying to print a set of contact sheets, page size is 9x6 we have it set to print 9 images + info on a page , we are using images outputted from Lightroom (jpegs) at 50% quality, when we print the page size becomes app 36mb and the page takes 0ver 5 mins to print does qimage not automatically reduce the image size to produce an acceptable image quality but with a better print speed (there is over 36 pages of images to print) we are only sending one page to the printer at a time.
If this is not possible are we going to have to resize the images ourselves before importing into qimage. (we use the studio version)

I await your reply

Just go to the interpolation and printing options and reduce the interpolation ppi to a lower value or even off. There are 6 options in the dialogue, see attached screen snap.
I don't think anyone would want Qimage to modify these values automatically, it's your choice, quality or speed.

Thanks for reply Terry M will change these and try , think i agree with you about auto image resizing , will let you know if it worked
Thanks

I've just tried this myself, I may have been wrong in my assumption (based on what  remember from the past), but changing the resolution did not seem to make much difference. Changing to a faster interpolation method should make a difference and using smaller images to start with helps a great deal. However, producing an extra set of images for the contact sheets does not seem worthwhile and takes time anyway.

There are a number of ways to speed up contact sheet printing.  If quality isn't paramount, I think I might turn interpolation ("res" parameters on main window) to "OFF".  That should result in a massive speed-up because Qimage won't try to antialias when downsampling.  I'm curious about the 5 minutes though.  I can't imagine 9 images taking 5 minutes to process even with the highest settings.  What kind of PC do you have: how fast is it?  And do you have the Studio Edition?  If you have a quad core PC for example, the Studio Edition will print up to 4 times as fast with hyper printing on.
