Judging decorative paper: start by holding the sheet up to the light

Hold the sheet to a light before you judge the pattern. Chain lines, struck-through color and grain direction, and why no shops are ranked here.

What to take away

  • Hold the sheet to a light before you judge the pattern. The structure of the paper tells you more than the decoration does.
  • Chain lines and a watermark mean a mold-made or handmade sheet, not a printed imitation.
  • No brands or shops are ranked here, because nothing was ordered or compared for this article.
  • Decorated paper is a substrate plus a surface, and buyers who only assess the surface get caught.

Read the sheet first

Decorative paper sells on its face, so the base sheet gets ignored. Hold it against a window, and the University of Warwick's material on characteristics of handmade paper describes what to look for.

A mold is a wire sieve on a removable frame called a deckle. The sheet keeps its imprint: closely set laid lines between the narrower sides, and thicker, more widely spaced chain lines along the length.

From the thirteenth century onward most paper also carried a watermark, formed by a wire pattern sewn onto the mold. Each mold was made by hand, so each leaves a different impression.

A modern machine-made sheet has none of that. Some have a printed imitation laid pattern, which sits on the surface rather than in the sheet and disappears when you turn the paper over.

What you are actually buying

Powders or smears

The struck-through test matters most for paste and marbled sheets. Color that has gone right through means the sheet was over-wetted, and it will be weak along those areas.

Substrate before surface

The paper under the decoration determines how the sheet behaves when you paste, fold and case it. The University of Utah's exhibit Paper is Fundamental quotes the printer William Everson, who called paper the ground of the being of the book and argued that critics fix on type while paper is more fundamental.

The exhibit also sets out what paper is: moist cellulose fibers drawn from vats of pulp, then pressed and dried. The process was developed in China during the Han dynasty and is attributed to the court official Cai Lun.

For a buyer, that means asking about fiber and weight before asking about pattern.

Why there are no shop recommendations

Ranking suppliers honestly means ordering from them, comparing what arrived against what was described, and repeating that over time. None of that was done. What is offered instead is the set of checks above, which work in any shop and do not go out of date.

Buying for a specific job

Endpapers
lighter weight, grain matching the book, color on one side only.
Covering boards
heavier, tolerant of paste, tested for struck-through color.
Box and slipcase linings
matte, low abrasion, dimensionally stable.
Practice
anything, including your own paste paper.

The formats those sheets end up in are described in eleven journal ideas, and the general property list is in choosing materials for book arts.

Common questions

Is handmade always better than mold-made?
No. Mold-made sheets are more consistent in thickness, which matters for a case. Handmade sheets are more variable and often more interesting.
Does a deckle edge mean handmade?
Not necessarily. Deckle edges are produced mechanically too, and a torn edge can imitate one closely.
Should I buy a sample pack?
Yes, once, from any supplier you plan to use. It answers the weight, grain and struck-through questions in one go.
How do I store decorated sheets?
Flat, interleaved, in the dark. Pigment offsets onto whatever is stacked against it.
