Grays do not plot accurately

Anonymous — Mon, 28 Sep 2020 09:11:05 GMT

Hello,

I have recently switched to Autocad 2021 and I am struggling to figure out what's wrong with the displaying and plotting of grays - particularly color 251, that displays too light (actually seems to display with the same value as 252). This happens in both model space and plot (printing to pdf) - but displays correctly in Layout space as well as plot preview as long as my plot style is set to "none".

So wrong display in autocad model space - correct display in layouts - correct display in plot preview - wrong display in pdf print.

I am attaching screenshots as well as my model, I copied a part of my model in a new file for this purpose and the issue is the same.

Thank you for advice!

You need to check if you have any screening set to the colors 251& 252 in the plot style "Monochrome+150.ctb". Click on the edit button next the plot style and check for screening🙂

Hi @Anonymous

Can you share the .ctb file(create it as zip and attach) so that we can test it from our end as well? Also, share the snapshot of the plot setup.

Check if AutoCAD is updated with the latest version available🙂

@vinodkl here are both files you have requested, thank you so much for your time! I do believe my autocad is up to date, I did not encounter this issue in the old (2015) version that I had actually 🙂
