Ink & Printing FAQs

Typical systems combine a pigment or dye, a carrier, a binder and additives that control properties such as flow, drying or adhesion. Their roles differ. Ask for the relevant technical and safety documents for the actual grade.

Water is a principal part of the carrier system. The ink can still contain binders, pigments, co-solvents and additives. Review the formulation and printing conditions rather than treating the label as proof of zero emissions or compostability.

A plant-oil component is used in a suitable formulation, commonly associated with offset systems. It does not mean the whole ink is soy or that the pigment is renewable. Confirm the fraction, grade and intended application.

The colorant can come from a renewable biomass-waste route instead of conventional fossil-derived carbon black. The ink still needs an appropriate carrier and binder. See the algae-ink guide for the developer’s technology and a project trial process.

A useful comparison needs the same print job and substrate. Consider formulation, production waste, energy, coverage, durability and finished-pack recovery. A single ranking can hide differences between a paper label and a flexible pouch.

The printing image may require a physical plate or other dedicated tooling. Setup is separate from the amount of packaging ordered. Confirm what is reusable on reorder and what changes require new tooling.

Digital can avoid some tooling and suit short or variable runs, but the result depends on consumables, energy, waste and substrate. Compare the actual quantity and production route.

Do not assume so. Adhesion, absorption, flexibility, drying and wash performance differ. Select a grade for the intended surface and confirm it with a physical trial.

A separate spot color can require another ink preparation and, in plate-based methods, another separation or plate and registration work. The effect depends on the process and whether that color is already part of a process-color setup. Ask for the actual job’s color and tooling breakdown.

Changing the image can require new job-specific tooling. A repeat order with unchanged approved artwork is different from a new image, size or repeat. Retain the file revision and ask which tooling remains reusable.

RGB describes light on screens. CMYK builds printed color from process inks. A spot-color system specifies a separately prepared color reference. Confirm the agreed system and a physical target when matching matters.

It provides a shared reference, but substrate, coating, ink and process affect the result. Agree on a physical sample and tolerance rather than relying on a code alone.

On dark, natural or transparent materials, white can act as a visible color or an underbase. Opacity and coverage depend on the process. Confirm where it prints and whether it changes detail or cost.

Minimum detail depends on the printing method, substrate and whether the element is positive or reversed. Request the process-specific guide and inspect a final-size sample.

It checks layout, wording, dimensions, orientation and color references. A physical sample is needed when exact shade, texture, finish, opacity or construction determines acceptance.

A reversed line is the unprinted gap within printed areas. Ink spread, substrate texture and process limits can close that gap. Use the process-specific minimum and inspect the actual-size output instead of judging a magnified screen view.

It is alignment between separate colors or operations. Small shifts can create colored edges or gaps. Designs requiring several colors to form tiny lettering are more sensitive than a single-color version.

A PDF can show intended layout and dimensions. It cannot reproduce fabric hand, board stiffness, exact foil reflection or seam quality. Review a physical sample when those features determine acceptance.

One approved specification, named final artwork, color target and relevant physical sample. State changes explicitly so a reorder is not interpreted from several inconsistent files.

No single carrier label establishes that. Assess the finished box and additions against the intended paper recovery system and applicable labeling rules.

Only with suitable evidence for the complete construction under the stated conditions, including ink coverage, adhesive and other additions. Local acceptance must also be confirmed.

It provides handling and hazard information for a substance or formulation within its scope. It is not a universal certificate of environmental performance, food-contact suitability or compostability.

Reducing unnecessary coverage can simplify a design and reduce ink use, but protection, readability and the chosen process still matter. Compare samples rather than assuming a fixed environmental saving.

The production operator should manage residues and wash streams according to the formulation and applicable waste rules. Finished-package disposal instructions address a different stage.
