I guess this is where these items are being reported.
When either of the two 25% fills are set with the background pen as transparent (0), the fill plots as solid black. All other fills that we have tested are fine with the transparent background pen. Also, the 25% fills plot fine with other background pens set. Our plotter is an HP700 monochrome.
I don't recall if this was the case in AC9.
AC25 v. 5005 w/ MEP, Cadimage, Twinmotion 2021 using AC from AC6.0, 2.7 GHz 12-Core Intel Xeon E5 (OS X 12.2.1 Monterey), AMD FirePro D700 6GB, SSD, Artlantis 2019, Adobe CC. Used AC on both platforms.

Yes they are now true bitmap halftones rather than vector dots (25%) or lines (50% & 75%).
Is the problem that they are printing properly but turning solid black when plotted (HPGL)?
Plotter drivers used to be a bit quirky about bitmaps, but I thought that was sorted out long ago. I have had no problems printing these fills so perhaps it's finally time to give up on HPGL. I know all the advantages of plotting (line weights, file sizes), but the future is PDF. Even HP is giving up on HPGL. It is now an extra cost option on their "large format printers" (they no longer make "plotters")
I should not have brought this topic over to the Spool Folder thread. But we can finish the discussion here.
It is a plotting bug and it needs fixed.
Yes, I understand pdf is the future and that is where we are headed. I use it all the time for smaller scale work. But we are not there yet, and until the technology catches up (file size/internet speed/print quality/exact scale/etc) I will be sticking with HPGL.
This may or may not be related, but goes well under this heading anyway.
I have a fill representing long run roofing assigned to the material on my roof, which seems to be having trouble expressing itself. It is simply parallel lines at 120mm crs. In my elevation as I zoom in it APPEARS to go from bitmap display to vectorial, although that is not necessarily what actually happens, just what appears to happen. So as I go from distant, scrolling/zooming-in the lines are far too dense, until I get to 900ish% zoom, then they suddenly display correctly. This happens in both Model and Layout views of my elevations.
The net result of this is that when I print, the roof surface prints solid black. Other fills in the same views, both assigned to materials and 2D overlays, seem o.k. This is very puzzling. Display and printing was OK in AC9.
That's only the zoom on the screen. I have to get that close to see the fill correctly. It's a large building, 1:200 scale for A3 output (still at sketch plan stage). As for a mod, I will see what I can do, working on something else at present.
We are having similar issues with certain composites anything with a 25% fill plots solid black but prints out okay. Printing is an okay short-term solution but the quality is not what it is with plotting. We are using an OCE TDS600.
We have found a couple of work arounds:
1. Changing Wall background fills to white will allow us to Plot okay.
2. Printing instead of plotting works without having to manually change all wall in a project. This is not a satisfactory long-term solution.

Was definitely not the case in AC9 as we have details that use the same fills that were fine in AC9 and not in AC10.
The transparent background does seem to be the problem, changing it to white brings back the original intended results.
In Addition to the 25% fill also effects the Gypsum Board fill (which is more or less the same fill) Have not tried other but I'd wouldn't be surprised if it didn't effect any of the similar fills (ie. small tightly regular spaced dots)
This is an acknowledged bug. It was not fixed in the 966 update. The recommended workaround is print or change the background fill. The negative for this of course is that the fill is no longer transparent.
Where can you control the SCREEN PERCENTAGE? I see the 25% grey, 50% Grey - This feature does not work the way the industry standard works. As far as I can see. Can anyone else fill in the facts about grey scale in ArchiCAD 10?
On my printed output, I would like to specify a newspaper type screen percentage. In traditional printing grey tones need to be screened for the press, 300 lines is a high amount per inch. Newspaper is about 60 lpi. So a 60 lpi grey tone (printed) would have a course dot pattern. All I can get is a very fine dot pattern- Looks like 150 lpi . Where can I control this output in the publisher?
