What Paper Type Is Best for Your Book? A Practical Printing Guide

Paper is one of the least discussed decisions in book production and one of the most noticeable to readers. It affects how a page feels in the hand, whether printing shows through from the other side, how photographs reproduce, how wide the spine becomes, how heavy each copy is and how much the whole print run costs. Readers may never know the name of the paper, but they notice when it is wrong.

Authors are often asked to approve paper on the strength of a single number in a quotation, such as 70 gsm or 80 gsm, without ever seeing the stock. That is a poor basis for a decision that will be repeated across hundreds of copies. Our recommendation at Sotrane Publishers is to choose paper with a printed sample in your hand and a clear idea of how the book will actually be used.

The best paper is not simply the heaviest or the most expensive. It is the paper that suits the way the book will be read, handled, printed and distributed.

Start with what the book has to do

Before asking which paper to use, describe the book. A 300-page novel that someone will read for hours needs a different interior from a 32-page children's picture book. A training manual carried into workshops has different demands from a commemorative photograph book. A school text may need enough opacity to stop diagrams on the back of the page distracting the reader, while a poetry collection may benefit from a softer, more tactile page.

A useful first conversation with a printer covers the final trim size, the approximate page count, whether printing is black and white or colour, how much photography or illustration the book contains, the expected quantity, the binding method, whether the book will be carried often or kept on a shelf, and your budget per copy. Without those details, "Which paper is best?" is too broad to answer.

What gsm tells you, and what it does not

Printers in Zambia, as in many other markets, usually describe paper by its weight in grams per square metre, written as gsm. It is a measure of weight. It is not a complete measure of thickness, opacity or quality.

Two papers of the same gsm can feel quite different because they differ in bulk, coating, fibre, smoothness and opacity. That matters most when working out the spine. A 300-page paperback has 150 leaves, since each leaf has a front and a back. If one paper is noticeably bulkier than another, the finished book will have a wider spine even though the page count has not changed. The cover artwork must be prepared to the actual spine width the printer confirms, which is why a full wraparound cover should not be finalised before the paper and binding are settled.

The right paper is the one that suits how this particular book will be read, carried and sold.

Uncoated paper for reading books

Uncoated paper has no glossy surface coating. It takes ink differently from coated stock and produces less glare under ordinary light. For novels, memoirs, biographies, poetry and most text-led books, uncoated paper is the sensible place to start. Depending on the mill and what the printer has available, a standard reading book is often printed on something in the region of 70 to 90 gsm. Treat that as a starting point for discussion rather than a rule.

White paper gives a clean, familiar look and suits many educational, professional and general non-fiction books. Cream or natural paper can feel softer for long reading, especially in fiction. Neither is automatically better. The choice is partly editorial and partly a matter of how the book should feel, so do not choose cream simply because another novel used it. Look at the actual stock under normal reading light, because a screen cannot show paper colour accurately.

Pay attention to opacity

Opacity describes how much printing from the other side of the leaf shows through. A light paper can still be comfortable to read if its opacity is good. Show-through becomes more noticeable in books with dense text, dark headings, tables or illustrations, and it can make a page look busy and tiring.

Rather than choosing by gsm alone, ask the printer how opaque the proposed stock will be with the amount of ink your pages carry. A printed sample answers that question far better than a specification sheet.

When a heavier uncoated paper makes sense

Workbooks, premium non-fiction, institutional publications and books with frequent charts or illustrations can benefit from a slightly heavier uncoated stock. Moving up in weight can improve the feel of the page and reduce show-through, but it has consequences. The spine becomes wider, each copy becomes heavier, cartons weigh more, transport and courier costs may rise and the printing cost per copy can increase.

Those consequences multiply with quantity. If you plan to send copies from Lusaka to Ndola, Kitwe, Livingstone and other towns, a small increase in the weight of each book becomes a significant increase across every carton. Paper is therefore a distribution decision as well as a reading one, which is easy to forget when the only sample on the desk is a single copy.

Coated paper for images

Coated paper has a smooth, treated surface on which ink sits differently, producing sharper photographs and stronger colour. It is worth considering for photograph books, art and design books, catalogues, some cookery books, illustrated educational material and children's books with strong full-colour artwork. Depending on the publication, a printer may suggest coated stock in the region of 115 to 170 gsm, or another specification suited to the press and binding.

Colour does not automatically mean glossy paper. Matt or silk coated stock reduces reflection and may suit a book better, and some illustrated books print very well on a good uncoated paper. Ask for a proof that includes one of your darkest images, a skin tone if relevant, a light image and a page of small text. That tells you far more than a printer's general sample.

The cover

The cover is printed on much heavier card than the interior. For many paperbacks, printers work with board somewhere in the region of 250 to 350 gsm and then apply a matt or gloss lamination, depending on the design and production method. Again, the number alone does not decide quality.

A cover needs enough stiffness to protect the book without fighting the binding. A very heavy cover on a small, thin book can feel awkward, while a weak cover on a thick manual that is handled daily may curl or tear quickly. Lamination changes the feel as well. Matt lamination is understated and reduces glare. Gloss intensifies colour and wipes clean easily, which can help children's and practical books. Any additional finish should have a clear purpose, not be added simply to make a quotation sound premium. If you are still deciding how the cover should work, read our guide to book cover design before approving the final artwork.

How to compare two printing quotations

When quotations arrive, compare the specifications before the totals. For each quotation, check the interior paper type and gsm, whether it is coated or uncoated, the cover board and gsm, the lamination or finish, the trim size, the page count assumed, the binding method, the number of colour pages, the quantity, whether VAT and delivery are included and whether a physical proof is provided before the full run.

The price difference matters. If one printer quotes K38 per copy and another K34, the K4 difference becomes K4,000 on 1,000 copies. But a lower price for a materially different book is not a saving. It is a different product. Make sure you are comparing the same specification before deciding.

Hold a physical sample before a large run

For any significant print run, one of the most useful things you can examine is a physical sample. A dummy is usually blank but made to the proposed trim size, page count and paper. A production proof contains your printed content. The exact options depend on the printer and the printing method.

Hold it and open it. Read several pages. Look at the text near the binding, check whether images show through and see whether the book stays reasonably open. Examine the cover crease and the spine. Put it in a bag and imagine carrying it to a lecture or a meeting. A quantity of copies chosen only for a low unit price is a poor saving if the paper makes the book uncomfortable to read or there is no realistic plan to distribute it.

Questions to ask your printer

Before approving production, ask questions that produce specific answers:

• Which exact paper are you proposing for the inside pages, and what is its gsm and finish?
• Do you have a printed sample on that stock?
• Is its opacity suitable for my page design?
• What spine width should my designer use with this paper and page count?
• How would a lighter or heavier paper change the cost and the bulk?
• Will this stock still be available if I need a reprint?
• Which cover board and lamination are included?
• Will the binding method suit the final thickness?
• Can I approve a physical proof before the full quantity is printed?

A professional printer should be able to explain the trade-offs rather than simply telling you that one paper is "the best".

When to make the decision

Paper belongs late enough in the publishing process that the page count, trim size and content are reasonably stable, but early enough that the designer can build the final cover to the printer's confirmed spine width. If the manuscript is still changing substantially, do not lock the specification too soon, because twenty or thirty extra pages can change the physical book.

When Sotrane prints a book, we confirm the trim size, page count, paper, binding, finish and quantity before issuing an itemised written quotation, and a proof is provided for approval so that paper, colour and finishing can be checked before the full run. Text-led books are commonly printed on cream or white uncoated paper, while books with significant photographic content usually benefit from coated stock. Our book printing service can help you weigh those choices against the purpose of your book.

The useful question is never simply "What is the highest-quality paper?" It is "Which paper gives this particular book the right reading experience, durability and cost?" That question is best answered with a sample in your hand.
