decrease minimum grid size
i think, it would be nice if the minimum grid size could be set to values smaller than 3mm.
I really like the high contrast that comes from half/toning of "rasterizing" the image and i would like to apply this also in application, where the "poster" is viewed from such a small distance that 3mm grid size is simply to small.
thanks in advance, if you could make this possible. Also, if the code was free or i could help contributing this, i would be flattered.
Depending on your printing setup, you can manually decrease the grid size (indirectly) by printing on a smaller print area or at a different scale, or printing multiple pages per sheet. Though this will drastically (multiplicatively) reduce your poster size, so you'll have to compensate for that in step 2. Also, you'll have to do a lot more cutting, because your printed "pages" will be small rectangles, several per piece of printed paper.
So my suggestion is far from a perfect solution, but it's achievable now.
