For deliberately rough artwork, define acceptable texture through an approved physical reference and distinguish artistic irregularity from unwanted printing or handling faults. A general instruction to make the canvas 'look rustic' leaves too much to interpretation. The studio and artist should therefore define what intentional irregularity looks like in a specific approved reference and distinguish it from defects introduced during printing, finishing or handling.
Define the artistic intention in observable terms
Ask the artist to identify the texture's role. Are broken ink-like edges supposed to evoke block printing, are scan marks retained to convey a hand-worked surface, or does a coarse brush image rely on uneven highlights? Mark a small number of important image regions in the source artwork and explain which irregularities must be preserved. This is more useful than an abstract promise that every part of the print will reproduce 'perfectly' despite the chosen material's surface.
Agree on whether the roughness exists in the digital image, is a characteristic of the physical canvas, or results from a selected finishing method. Those sources of texture have different controls. A simulated gouache brushstroke printed onto fabric should not be described as real raised paint unless such a finishing process was actually specified. Establish the intended viewing distance and whether fine details need to remain legible at arm's length; what looks expressive at distance can become distracting close up.
A linocut-style canvas intentionally reproduces broken black edges and patches of uneven ink. The artist signs off a sample in which a particular branch has a jagged contour, but the delivered edition includes an extra glossy streak across the central figure. Annotate both regions on the approved reference: one is an intentional source feature, the other requires review because it was not authorized. Establish the viewing light and distance used for comparison and document who will decide borderline cases. Avoid a vague standard that any rough-looking mark is acceptable because the artwork is rustic.
Use a signed reference and defect boundaries
Prepare a representative physical proof that includes a rough area, a smoother color region, a fine line and any type or signature. Document the exact file version, substrate, coating and color setup used for that proof. The artist can annotate acceptable broken-edge patterns, expected grain visibility and tonal variation. The studio should separately define unacceptable issues such as missing image content, foreign marks, distorted dimensions, unapproved cropping or unintended adhesive residue.
Where the job calls for measurable tolerances, the production parties should choose valid methods and units in advance. A loose promise that 'minor variation is normal' cannot decide every case. If they cannot reliably quantify texture appearance, an agreed master sample and side-by-side viewing protocol may be more practical than invented numerical limits. Capture who approved the reference, the approval date and what changes would trigger a new sample.
Document inspection and resolve borderline cases
Inspect the delivered print under the same viewing conditions agreed for the proof, then note which differences relate to intentional source artwork and which appear only in production. Compare the same image area at matched magnification. A scratch crossing a face that did not appear in the signed reference is different from a scanned brush mark already present in the file. Likewise, a texture made more prominent by a new coating might be artistically significant even if no literal pixels are missing.
Create a short exception process: photograph the disputed detail, identify its location, cross-reference the approved sample, and send it to the named artist or production reviewer. Do not erase the question by declaring all unevenness intentional. Keep a record of the final decision—accepted character, approved deviation, reproof required, or remake requested—so a replacement can be evaluated consistently without relying on memories of an informal conversation.
The agreed threshold should protect expression and workmanship at the same time. A signed physical reference, annotated intentional textures and clearly separate defect boundaries let both sides preserve the artwork's rough character without excusing a fault merely because the image was never meant to look smooth.
