Paper Types

The in-house paper stocks Printorium Bookworks uses in its book production allows for excellent print quality. We carry white, cream and coated paper stocks, some with recycled content. If you require a special stock, please contact your account representative for custom paper selections and applicable pricing.

  • Our standard in-house paper stock for the printing black & white text and/or images on the inside pages is a 60lb. 100% Recycled Post Consumer Waste white offset sheet with a 94 brightness. The sheet is acid free and elemental chlorine free. Also available in 50lb. and 70lb. weight.

  • For the inside pages in colour books, our in-house sheet is an 80lb. in either a Silk or Gloss finish with a 10% Recycled Post Consumer Waste and is acid free and elemental chlorine free in a 91 brightness. Both the silk and gloss are also available in a 100lb. weight.

  • Covers are printed on a 10pt. C1S (Coated 1 side) cover stock. The cover stock is elemental chlorine free in 94 brightness. The cover stock is also available in 12pt. C1S.

Did You Know? The basis weight of a paper (ie. "60lbs" or sometimes listed as "60#") is the designated fixed weight of 500 sheets in that paper's basic sheet size. But the "basic sheet size" is not the same for all types of paper and some types of paper come in a variety of sheet sizes! Even if the numbers look like they mean the same thing, always ask your printer to recommend a stock if you're not sure.

Finished Trim Sizes

Books fall into three pricing groups based on size thresholds. Once any threshold is exceeded, the pricing for the book goes into the next largest book group (width in inches x height in inches).

Please note: While pricing is based on the size groups, the exact trim size is required for accurate quotes and printing.


GROUP A

4" x 6" but smaller than (or equal to) 5 1/4" x 8 1/4"

GROUP B

Larger than 5 1/4" x 8 1/4" but smaller than (or equal to) 6" x 9"

GROUP C

Larger than 6" x 9" but smaller than (or equal to) 8 1/2" x 11"

Laminated Covers

Printorium Bookworks offers both gloss and matte laminates for book covers. Used as both a protector and an enhancer, it is a highly recommended option. Before deciding if it's necessary for your printing, consider how often the book will be handled as laminate adds both durability and longevity to the cover.
