Mike Chaney's Tech Corner

I would like an option to specify an overlap when printing poster prints.

Anyone else like to have this feature added?

Some printer drivers have this feature. I have a little Canon printer that can do this; just checked my Epson R800, that has the same facility. It would be worth checking your driver too. In both my cases, it was on the Page Layout tab.

I don't mean just a white border.

Qimage doesn't print an overlap in the image. It effectively slices the image.
I find it difficult (and expensive) to print and join accurately. There's always a sliver missing ..or if I join after leaving a white border I might get a white sliver at the join.

It would just be so much easier to join with a proper overlap in the image itself.

Ok. I see what you mean.
But overlapping produces a step in the surface that may look worse than a missing sliver.

There is a way to do it in Qimage from the batch filter but it means making however many images you require sections of the poster.
If, say it's 4 sections, make 4 separate crops of the image and save as separate images. When cropping in the batch filter, a read-out of the pixel size is given, just allow the appropriate overlap in pixels on the edges that will overlap.
I have actually done this in the past, not to make a poster, but just to test the technique, put them together on a page in Qimage and then printed to file to test the accuracy - perfect  ;D
How about that?

Since my previous post it has occurred to me wrt:
Having done just a few poster prints, I agree it's difficult but felt I was limited by my modest cutter.
You might want to review both your cutting equipment and technique, I hope someone with regular experience on this will contribute.

Thanks for your replies Terry.
My 'traditional' way of joining in to overlap on a light box 'tack' the back with masking tape and cut down the middle of the overlap. There's no step. No bit missing. No 'white' bits.
Of course it's possible to do it manually as I have been doing ..but it would be a nice option when poster printing.
Come on Mike make my day!! ..please

Well, I've learnt something today, thanks  ;D
