We have a wide range of papers with differences in texture, density and quality. Certain types of papers tend to work better with certain types of projects - we'd be happy to make a recommendation as to the best fit for your work; alternatively, should you have a specific type of paper in mind, do let us know!
The maximum printable area is 400mm x 277mm; and because the risograpgh printing technique cannot produce fully-bled artwork, please do leave a white border of at least 10mm all around. Minimum Type Size Generally speaking, a risograph printer will struggle to accurately reproduce very small type below 6pt.
We'll need the original artwork for all your prints: please send us your files in a .psd format as we are running Adobe CS6. For each layer of colour, please specify which riso colour you'd like us to print it in. You don't need to match the exact colours in the document - naming them accordingly within the layers will suffice. Please also provide proofs of all your artwork.
The nature of risograph - given that it was intended for single colour printing - is such that multiple colour printing always runs the risk of misregistration. You could, of course account for this through bleeding and trapping. Keep in mind that the more colours you include in your print, the more it'll have to pass through the risograph: this increases the chances of the roller leaving light tracks upon your work - and these stains, unfortunately can be very difficult to remove.
We also don't recommend printing a large area of solid ink - most especially if your prints are double-sided (books, leaflets, magazines and such things). Perfectly backing up artwork is very difficult as well - do keep this in mind during the design process. If you'd like to use a larger area of colour, perhaps you'd like to consider 70-80% tints instead.
We can facilitate most types of finishing for your project: Binding, foiling, embossing, just etc. Give us a call to find out what's possible.
