Choosing the right paper for the job

Deciding which paper stock to use for your job can be tricky. How thick is 135kg? How matt is Matt-Coat? We have put together this guide to help address these questions and more, when choosing from the many types of paper we offer here at Mojoprint.

Guide to Japanese paper weights (kg)

How on earth can a piece of paper weigh 220kg?! Well, it can't, but a stack of 1000 press sheets can. The way paper weights are expressed can be a little confusing, particularly as many designers working overseas may be used to gsm (grams per square meter) rather than kg weights.

Japanese papers are classified according to the weight of a stack of 1000 pieces of benchmark sized sheets laid on top of each other. There are many different paper sizes in use by commercial printers in Japan, each affecting the weight of a stack - and thus the xxkg weight of any one sheet paper. We use the shi-roku-ban paper size (approx 788 x 1091) as the bench mark for expressing our paper weights.

See our GSM to KG paper weight conversion table for more details.
