Two fabric quotations show the same illustrated pattern. One names a reactive dye system; the other names textile pigment ink. Both are described as digital printing. Before choosing between them for a cotton tote, the buyer needs to know what those proposals include after the image has been printed.
Cotton tote pigment and reactive printing should be compared as complete, identified fabric proposals. The image file alone does not define the colourant, fixation, finishing or cloth that will arrive at the cutting table. Confirm first whether either route can be considered for the project; a printed swatch from another supplier is not evidence of Gahumi’s production capability.
Identify how the proposed colour is fixed
Mimaki’s reactive dye information lists cotton as a suitable substrate for its named systems and describes dye bonding with fibres. Its textile pigment information instead describes a binder-containing system fixed with heat. These manufacturer examples explain why the words reactive and pigment are not interchangeable.
Do not transfer the manufacturer’s performance or certification statements to an unidentified tote. Ask the actual fabric provider to name the proposed system, base cloth and any required preparation and finishing. The decision is about this material combination, not a claim that one whole category is always brighter, softer or more sustainable.
A reactive printed cotton fabric brief should keep the ink or dye-system identity connected to the fabric reference. A pigment printed cotton fabric brief needs the same clarity, including the relevant binder-based proposal. If a provider cannot supply part of the information, identify the gap before accepting the sample as a production reference.
Follow the fabric through to its usable state
Ask each provider to list the actual steps between printing and delivery of finished cloth. Include the responsibility for any fixation, washing, drying or other finishing required by that proposal. Do not copy a sequence or machine setting from a different ink system.
The pigment manufacturer’s page itself notes that steaming and washing needs can depend on the print type. That is a reason to confirm the proposed route, not to describe all pigment printing as free of those operations. The buyer needs a completed material proposal with a named party responsible for its release.
For a fabric printing process handoff, request three connected records:
- The identity and composition of the unprinted cloth, its shade and the side to be printed.
- The named printing and finishing proposal, including the point at which the cloth is considered ready for cutting.
- The final fabric sample reference and the checks agreed before that release.
Any finishing that may affect the usable dimensions belongs in the sample discussion. The dimensional-change guide helps frame an appropriate assessment; this comparison does not assign a shrinkage value to either route.
Compare finished cloth, then the assembled tote
A cotton tote print strike-off comparison should use the intended artwork scale and clearly identified cloth proposals. Compare important colours, fine elements, larger filled areas and the feel of the fabric. If the base cloth or finish differs, show that difference on the comparison record rather than attributing everything to the ink category.
Can a pigment fabric sample approve a reactive-printed tote? No. It can communicate a desired appearance, but the proposed replacement material and process need their own review. Keep the two samples separately identified until the buying team accepts a specific combination.
Request a completed tote using the selected finished cloth. Inspect how the illustration appears across the actual panels and folds. The repeat-print guide addresses motif scale, direction and seams; those layout approvals do not establish the material system used to produce them.
Agree the evidence needed for care and colour transfer on the selected finished bag. Use the rubbing-colourfastness brief for that separate question rather than assuming an ink family guarantees a result.
If a 100% cotton body is required, confirm its composition separately from the print, handles, sewing thread and trims. A reusable design can be developed around useful dimensions and supported care. Neither digital printing nor the chosen colourant establishes a comparative environmental advantage.
Share the cloth proposals, authorised artwork, intended bag construction and quantities with Gahumi. Include the destination and arrival requirement. Ask which material route can be assessed and what sample development, evidence and quotation would be needed before choosing it.
