Black & white PDF bug in V12

[Barry Kelly]

Can anyone else please confirm thisas being a problem (bug)?
I want to publish all my PDF as balck & white or grey scale.

When publishing a PDF with the built in converter, set the document options to print the PDF in "Black & White".
Print a layout where the drawing is displayed in colour.
The drawing must contain walls with a solid fill that is not black (this only seems to be a problem with fills).

All the coloured fills appear white (empty).

However set the print options to colour or grey scale and it prints as expected.

See attached image for an example.
The left is a coloured layout printed as black and white.
The centre is the same layout printed as colour (and as it appears in Archicad).
And the right printed as grey scale.

The simple solution is to have a pen set for black / white / greyscale pens that can be used to display the drawings in the layouts as I want them to print.
Then print these with the document settings as "Colour".
Then they will all print black / white / grey as displayed.

It's not a big problem to over come but I just to confirm that it is a problem and not something I am doing wrong.

By the way there is no such problem in V11.

Barry.

Printing colors as B/W or grays is often troublesome in various programs on various printers (though more so now in AC12 it seems) and probably always will be. This is why your practice of assigning pen sets to control the output is the way to go. Not only is it more predictable, it provides vastly more control of the output quality. This is why I have recommended this approach as an exclusive practice for almost 20 years.

True that, though as a relative newcomer, I've only been doing it this way for 17 years. This approach (for me anyway) was born out of the use of old pen plotters. You controlled the density that the line would appear once blueprinted by the color of the pen (ie blue was light, yellow dark). Still the results were very unpredictable. Mapping your colors (in model space) to grey and black in the Layout space takes most of the guesswork out of it. I never convert the colors at the printing stage, always at the layout stage.
