Printing to PDF and Plotting

I have two drawings, both with an OS map attached. Both drawing have the same colour table attached to them , the same print attributes etc. 

Drawing "a" has a colour 126 (grey) associated to the OS, drawing "b" has a colour 144 (darker grey) associated to the OS.

In the PDF both drawings look great but when I plot from PDF to printer..drawing "b" OS comes out lighter than drawing "a" OS..

Any ideas?? Been bothering me a while

EDIT - This is using Microstation

  • Apologies, I meant to say above that it was colour table not pen table.. 

  • there are 2 places you can specify colour map when printing, pen table or the plot config. I assume you don't use pen table, so might work checking if there's any colour mapping done within your plot config. 

  • no overrides?

    could be a video card driver  thing ..

    Let me see if this is what your saying..

    while viewing the pdf not the print preview, the pdf looks as desired, but when you send the pdf to a printer  it comes out different..

    Some colour laser printers have several settings, ie default , images, enhanced and  CAD.. you printer may be set on CAD or enhanced.. this will produce  prints the match much closer to the cad view colours etc but if not the same settings for everybody  will produce variations depending on who printed it.. use to happen all the time when I worked at another company using  Minolta printers... especially  different shades of green  were vary noticeable...

    in order to some testing I suggest you make a new drawing using same seed  colour table etc.

    run this old macro.. sorry don't have a vba one handy.. you have to unzip it put it where all your macros live and keyin macro drwtable it will then produce colour swatches with their rgb values below the little rectangles

    I suggest  you create pdf and try  printing the resultant pdf to different  printers and from different  users to those printers and compare results on the papers... this will not work in connect edition .. bas has been removed form CE  only vba available... must be a  vba version on the forum somewhere..........aha!

  • Lorys,

    Thanks for the above.. Yes you are right to assume that the PDF looks desired bit when sent a the printer it comes out different.

    When I print it off the colours come out fine and it does for others in my office, I have a colleague who works in a different office and its him that's having the problem. I looked at his PDF print settings yesterday and the are different to the ones I have, so that confirms what you said above. Seems to be that I have colour adjustments and he doesn't.

    I will test the vba and see what happens

    Kind Regards
