Photo book quality: how to judge a sample before you pay
Quality shows in paper, binding, print method, colour and cropping. Ask for the paper's gsm and finish and how pages are printed, then order a sample or one copy and inspect it in daylight.
Product pages describe quality in adjectives. Ask for names and numbers instead: the paper's weight and finish, the binding method, and whether pages are printed on a press or on photographic paper.
No printer can rescue a blurred photo or a careless crop. Much of a book's quality is decided by the files it is sent.
Make your photobook
Arrange your photos on A4 pages, check the proof and order a printed copy.
| What | How to check | Good sign | Warning sign |
|---|---|---|---|
| Paper | Ask for a sample of the exact stock | Comfortable page turning and suitable opacity | A paper specification without a sample |
| Show-through | Read normally with a dark image behind the page | Reverse photo barely visible | Dark shapes clearly visible |
| Finish | Look at a dark photo under a lamp | Detail visible without glare | Glare hides the photo |
| Fine detail | Compare the print with the exact source crop | Small detail stays legible at reading distance | Extra banding or lost detail absent from the source |
| Shadows | Look at the darkest photo | Some detail in dark clothing | Shadows a solid black block |
| Colour | Compare repeated copies of one reference photo | Skin and greys consistent | Green or pink cast on some pages |
| Binding | Turn pages gently and inspect the hinges | No lifting or cracking | Pages loosen or glue shows |
| Fold | Check faces near the centre | Little of the photo lost | Centre of the spread swallowed |
| Trim | Check text and heads at edges | Even margins on every page | Edges clipped or uneven |
Paper: weight, finish and show-through
Gsm is weight per square metre, not a quality grade. Compare opacity, surface and stiffness on samples of the actual paper; heavier alone does not settle any of those.
Read a page normally under a lamp with a dark photo on its reverse. Backlighting exaggerates show-through, so use ordinary reading conditions for your decision.
Tilt a sample page in the intended reading light. Check whether reflections obscure the picture and whether handling marks bother you on that particular finish.
Inspect the actual printed detail
Ask which print process and paper the sample uses. A supplier may offer press, photographic or inkjet products; the appearance of one does not establish the quality of another.
Check the smallest text, fine hair and straight edges at normal reading distance, then closer. Look for lost detail, visible banding and rough transitions where the source image was smooth.
Compare the darkest areas with the submitted file. If a jacket is already featureless in the original, printing cannot reveal detail that the file does not contain.
Binding you can test by hand
Turn the sample pages gently and inspect the hinges without forcing the spine flat. Look for loose sheets, splits, rough edges and glue marks, then ask the printer about any defect.
Look at how much of each photo disappears into the fold. In a well-bound book the curve is gentle; in a tight one a face near the centre is lost.
Close it on a flat table. The cover should sit square, with corners that meet and no boards that rock.
Colour and cropping
Repeat the same reference photo in your test rather than comparing different lighting on different faces. Look for unexpected casts or inconsistency between identical images.
Check what the printer cut. Trimming varies slightly from copy to copy, so a head or a word right at the edge of the page may be clipped on one copy and not another.
A test before a big order
For an expensive book or many copies, make a short book at the printer's minimum page count first. Put the hardest photos in it.
Include a dark night photo, a bright sky, close-up faces, a black and white photo, a page of small text and one photo across a spread. These show faults that easy photos hide.
Log faults by page, photo file and viewing light. Compare the original crop before calling a soft face a printing fault; the blur may already be in the source.
Steps
Ask for the specification
Ask each shortlisted printer for paper weight, finish, print method and binding for the exact book you want, not the range.
Build a hard test
Pick a dark photo, a bright sky, close faces, a black and white photo and a page of small text. Use them in a sample or a short book.
Inspect in two lights
Check the copy by a window and under the lamp where it will be read. Log each fault by page and source file, then compare the exact submitted crop.
Decide on the evidence
Order the full book from the printer whose test passed. Note any fault that appeared and fix the files before ordering, not after.
Questions
Is a lay-flat binding higher quality than a standard one?
It is a different binding, not a higher grade. It suits photos that cross both pages; a well-made glued or sewn book on good paper can be just as durable.
Does a higher gsm always mean better paper?
Not on its own. Gsm is weight, not thickness or finish. Compare papers of the same kind, and check show-through and stiffness in your hand.
Is photographic paper better than press printing?
They are different processes and stocks. Compare samples of the exact products with your own difficult images; the process name alone does not settle colour, detail, feel or durability.
