printing marks not properly aligned

Asked by Michael Ots on 2017-03-13

When I add printing marks to my design, they are not properly aligned. top-left is ok, but on the right en bottom side the printing marks are off by a few mm. This happens both when I Position it on the canvas and on a selection.

Hi Michael,

which Inkscape version are you using?

And what is your document unit?

Do you use a custom template?

Which extension are you using to create the print marks? They look a little different from what I can create via Extensions -> Render -> Layout -> Printing Marks (which works perfectly for me).

Regards,
 Maren

Hi Maren,

Inkscape version: 0.92
units are mm
No custom template

The extension used is the default extension in IS 0.92: Menu->Extensions->Render->Layout->Printing Marks...

I've added the svg file to the shared dropbox.

Okay, I see, thank you for your reply.

I believe the issue is with the unit change in Inkscape 0.92.
The file has been created with Inkscape 0.91, where a different resolution has been used (90dpi vs. 96dpi). This is reflected in the ratio of the position of the printing marks where they are vs. where they should be.

(the document unit is actually pixel, not mm.)

The document does not appear to have been converted to use the new scale (please correct if I'm wrong).

What works for me is:
- use the extension 'Document -> 90dpi to 96 dpi' (I'm not sure if there could be any negative consequences of using it, though)
- or: create a new document in 0.92 and import the old SVG into it. This will not keep the current layer structure (layers will be turned into groups), but it's probably safe.

I do not know if there is - additionally - a bug with the printing marks extension, or if this is to be expected if a document has not been converted properly. If you'd like to know, you can make a bug report at https://bugs.launchpad.net/inkscape .

Kind Regards,
 Maren

Thanks Hachmann, that solved my question.

The conversion did not work, then all print marks are concentrated around the selection origin. Importing on a new document did work. Disadvantage is indeed the fact that all layers are gone, but it is an acceptable workaround.

The conversion, followed by a new run of Print Marks worked for me. Thanks!
