Collagraph vs Monotype
コラグラフ / モノタイプ
Both sit in Print Expression, so the question is not what they belong to but how they behave. They are reached for with some of the same intent, which is where they get confused.
Collagraph
A print made from a matrix built or textured with materials such as paper, fabric or string. Their edges and surfaces carry the image; relief and intaglio inking can be combined. The assembled matrix is printed, distinguishing it from a collage displayed as the finished work or photographic collotype.
Monotype
Ink or paint is added to or removed from a smooth plate, then transferred to paper. Brushwork, wiped highlights and interrupted edges combine in a largely unique impression. Residual ink can yield a paler ghost print; this differs from repeatedly printing a fixed matrix image.

| Kind | Technique | Technique |
| Cues | Edges of attached materials appear in the print / Paper or fabric surface textures / Tone from ink held by relief and recesses / Lines, areas and pressure marks interact | Marks added or wiped on the plate / Broken contours and broad tones / Brushwork combined with transfer texture / Fainter residual ghost impressions |

| Type | Keep lettering in the work separate from added labels; place medium, artist and date outside the image. | Keep lettering in the work separate from added labels; place medium, artist and date outside the image. |
| Composition | Test material edges, relief and ink retention separately before combining them. | Test added marks and wiped highlights separately, checking reversal after transfer. |
| Material | Check the collection medium record and the paper and ink; do not infer materials from screen colour alone. | Check the collection medium record and the paper and ink; do not infer materials from screen colour alone. |
| Caution | A textured image alone is insufficient. Record the matrix materials and inking method; do not confuse collagraph with collotype. | Not every one-off print is a monotype. Distinguish a smooth painted plate from a fixed matrix varied as a monoprint. |
