Jigsaw Puzzle Board Types: Blue Board, Greyboard, and White-Core
By Giftenova Team – Published August 26, 2026
Blue board, greyboard, chipboard, and white-core are terms used for cardboard puzzle stock. This guide explains what the names describe, what they cannot tell you on their own, and which board Giftenova custom photo puzzles are die cut from.
What Are Puzzle Board Types?
Puzzle board terms describe aspects of the cardboard stock a jigsaw is die cut from, especially its core or backing color. Blue board, greyboard or chipboard, and white-core are common descriptions. They are sometimes grouped under the phrase jigsaw puzzle board grades, but no industry-wide standard governs those grades.
The same term can cover stock with different thickness, density, and construction from one supplier or maker to the next. Product pages may also use the broader phrase puzzle-grade card stock without naming a core color.
Board type is one part of the larger materials picture; our guide to what custom photo puzzles are made of covers the full build, from the card stock to the gift box.
How Board Stock Shapes the Finished Puzzle
Board stock shapes a finished puzzle through properties such as density, stiffness, thickness, and construction. A firmer board generally takes a cleaner die cut, and the quality of that cut helps determine how the pieces behave on the table. The board meets the die during cutting, a step covered in full in our guide to how jigsaw puzzles are made. Four effects can follow from the stock:
- Piece rigidity: dense board resists bending when a piece is picked up or pressed into place, while soft board flexes and can crease.
- Edge flaking: soft board tends to fray along its cut edges after repeated handling, while firmer stock generally keeps its edges longer.
- Puzzle dust: softer board tends to shed more fiber during cutting, which is the short version of why puzzles have dust.
- Fit consistency: a clean cut through firm stock gives the interlocking pieces a snug, consistent fit, while stock that compresses under the blade tends to cut less precisely.
Common Puzzle Board Terms
Blue board, greyboard or chipboard, and white-core are common puzzle-board terms. They are useful descriptions, but none guarantees a particular thickness, density, or finished quality.
Blue Board
Blue board is puzzle stock named for its blue to blue-grey core or backing. Available specifications vary by supplier, so the color alone does not establish density, thickness, cut quality, or piece fit.
Grey Board and Chipboard
Greyboard is the common one-word spelling for grey paperboard. Puzzle descriptions also use chipboard for this general family of board, although terminology varies by maker and supplier. Its density and thickness can vary widely, so the name alone does not tell you how firm a finished piece will feel.
White-Core Board
White-core board is puzzle stock described by its bright white core rather than a grey or blue one. As with the other terms, core color alone does not establish density, thickness, or cut quality.
Blue Board vs Greyboard vs White-Core at a Glance
The terms compare most reliably by the visible color they describe and the properties they leave unanswered.
| Board term | Visible clue | What the term describes | What it does not establish |
|---|---|---|---|
| Blue board | Blue to blue-grey | Blue core or backing color | Density, thickness, or cut quality |
| Greyboard or chipboard | Grey | Grey paperboard family | Density, thickness, or durability |
| White-core board | White | White core or backing color | Density, thickness, or cut quality |
Density, construction, and cut precision matter more than core color alone. Board terms do not specify a fixed thickness; how thick jigsaw puzzle pieces are is its own question with its own answer.
What Board Do Custom Photo Puzzles Use?
Giftenova custom photo puzzles are die cut from 1.5 mm blue puzzle board, and the photo is UV printed directly on the board. The same board is used across every piece count, from the 99-piece tube version to the 1000-piece box.
UV printing is a direct application method: the ink goes onto the board itself rather than onto a paper sheet that is then glued to the board, the conventional build for most mass-produced retail puzzles. The pieces are die-cut for tight interlock, and the printed face has a matte finish that helps reduce glare.
Turn over any piece from a personalized photo puzzle in the range and the blue/grayish backing is the visible sign of the stock. Every photo jigsaw puzzle in the custom photo puzzles collection is cut from the same 1.5 mm blue puzzle board, whichever piece count you pick.
How to Check the Board on a Puzzle You Own
You can read a lot about a puzzle's board in about a minute, without any tools.
- Look at the backing color. A blue-grey back points toward blue board stock, a plain grey back toward chipboard, and a bright white core toward white-core stock; treat the color as a first clue rather than a final answer.
- Feel the edge rigidity. Flex a piece gently between finger and thumb; dense board resists bending, while soft board gives easily and may start to fray along the cut edges after a build or two.
- Note the dust level in the box. A tiny amount of fine dust is normal for a freshly die-cut cardboard puzzle, while heavy shedding that continues after several builds tends to point toward softer stock.

Frequently Asked Questions
What is blueboard on a puzzle?
Blueboard is the one-word spelling of blue board, a term for cardboard puzzle stock with a blue to blue-grey core or backing. No industry-wide standard fixes its density, thickness, or construction, so a maker's published specifications matter more than the color name alone.
Is blue board thicker than chipboard?
Not necessarily. The names describe the stock or its core color, not a fixed thickness, and both blue board and greyboard are available in multiple thicknesses. Compare the maker's stated thickness and construction rather than inferring either from color.
What board are Giftenova puzzles cut from?
Giftenova custom photo puzzles are die cut from 1.5 mm blue puzzle board with a blue/grayish backing, and the photo is UV printed directly on the board. The same board is used for every piece count: 99, 100 XL, 500, and 1000.
