... : 9 Jun 2020 12:00 from: Martin Wynne Hi Gordon, Something very wrong there. It looks like the 5.4% is being applied in the wrong direction. It all worked fine on my Canon printer here. Don't change anything until I get back to you. There is certainly no need to redraw the plan. cheers, Martin. posted: 9 Jun 2020 12:42 from: Martin Wynne Hi Gordon, The reason for your alarming first result is that you may have inadvertently unticked this menu item: 2_090736_210000000.png It needs to remain ticked when making large-scale changes to the output size. It is ticked by default. That still doesn't get you to 7mm lines, I'm sorry I had forgotten you were doing aspect-ratio changes on the sketchboard. You can do them for the normal printing using the data distortions. I will post a full recipe shortly. cheers, Martin. posted: 9 Jun 2020 13:30 from: Gordon S I beg your pardon...inadvertently unticked this menu item? .. ...
