IDML + Preflight: Non-proportional scaling warning


Recommended Posts

I opened an IDML with APu and the Preflight Panel gives lots of warnings about non-proportional scaling of images. I have looked up one file to see what is wrong.

The original image in Indesign has a scaling of 20,77510066510341 % for width and height. The scaling information in the toolbar says 2048 x 2042 dpi and 15% x 15% scaling, the preflight warns about 14,6% x 14,7% non-proportional scaling. O.o

Second thing found: When I now want to adapt the dpi values in the toolbar (value linking off) to equal values, sometimes I have to make two attempts. Sometimes, but not always the dpi value gets reduced by 1 pixel, although the correct value is entered. So I have to enter the value again.

Erm, this is embarrassing. Forgot to mention a few extra steps. The problem is not the IDML import and non-proportional scaling ... The IDML was A4 and 600dpi. I changed to 300dpi and and scaled down to A5 bilinear. Seems to be a rounding error.

Sorry for wasting your time. :$
