When adding a gallery mirror inner border to an image, the image size is changing.
I'm using a Canon Pro 4600 - AI is not supported on this model - just in case this is relevent?

Example of issue but occurs on different roll media/sizes:
Using 24" matt paper roll
Set width 609
Set auto roll length

Print size - 297 x 420mm (A3)
Add required image.
Image popup confirms correct image size.

Select image. Add gallery mirror inner border - 25mm
Dimensions now 470 x 309.1mm
Expecting 470 x 347 (+50 border)

Select image. Reselect 297x420 print size.
Size changes to 470 x 325.9
Still wrong

Repeat above:
Select image. Reselect 297x420 print size.
Size changes to 470 x 334.3
Still wrong

Repeat above:
Select image. Reselect 297x420 print size.
Size changes to 470 x 347


Why does size change when adding the borders (set to B+ to add to outside)?
Why do I have to press the 297x420mm print size 3 times to get 297x420?

Thanks

Thanks.

Ummm... how do you turn off auto length...?
If I simply type my own (longer) length in, it reverts to the previous value when I click the confirmation tick button.

Oh wow!!! Cryptic!!!
I hadn't even noticed it changed colour (shade) to show on/off.

Was about to post another query regarding page sizes - turns out I had auto length on and it kept over-riding my settings...!!!

Live & learn...

Thanks
