Finally time to continue noting down my riso experiments thus far. One of my favourite features of risograph is that it can print on a much greater variety of paper stocks than a ‘normal’ printer. Uncoated paper types are the best, as they allow the ink to absorb into the paper.
RZ 570EP can according to its specs print on paper weighing between 46 g/m2 and 210 g/m2. Three of the samples I’ll show are within this range and the other two over the maximum limit.
These samples show orange ink printed on black Canson paper, uncoated, thickness I’d estimate about 140-160 g/m2.

This was originally a collage, and the print imitates the different textures rather well. Here is a closeup of one piece as well.

This one is riso print on Fabriano Elle Erre, a rather thick textured paper that is mostly used for charcoal drawings, thickness 220 g/m2. As the design (mistakenly) had a thick dark blue stripe on the top, this printed uniformly, but afterwards the paper got stuck and the coverage became uneven. I don’t even want to think about how much ink one of these prints takes, as it is A LOT.
A piece of image here:

And a closeup:

The following one is printed on “White Rose” (Russian brand) canvas-textured watercolour paper (unusual texture for that), 260 g/m2. Coverage was – as expected – uneven like on Elle Erre.

And a closeup:

Pastel paper stock, however, was a different story. Quite much thinner than the previous ones (estimated 100 g/m2), textured, uncoated – riso loved it. This particular paper was actually leftovers from book covers, but the texture reminds very closely that of Ingram pastel paper.

And closeup (the dots are back!):

The last one is “White Rose” watercolour paper, cold-pressed with a typical texture, 200g/m2. The image here is the same as on the black paper example. This type and thickness is great for riso art prints. (The unevenness of colour in the down right corner might speak against is, but the other images in the same print run did not have it.)

And a closeup again:

And that’s it for this time.
