A logo can look perfect on a laptop and still produce a disappointing result on fabric, metal or plastic. Screens display light through neat pixels, while physical decoration must work with ink, thread, heat, texture and curved surfaces. Small details may fill in, colours can shift and hairline text can vanish. Preparing artwork for promotional printing is therefore more than exporting the largest file available. It means understanding how the design will be reproduced, simplifying where necessary and giving the production team enough information to make reliable choices.
The first distinction is between vector and raster artwork. Vector files describe shapes mathematically, so they can be enlarged without becoming blocky. Formats such as AI, EPS, SVG and many PDFs may contain vector artwork, although a raster image can also be placed inside them. Raster files, including JPEG and PNG, are made from pixels and have a fixed resolution. They can work for full-colour digital printing when supplied at the correct size, but enlarging a small web image will not create missing detail. A high pixel count must be considered alongside the dimensions at which the image will actually print.
Before sending files for products sourced through GoPromotional branded products or any other production route, ask which decoration method is proposed and request its artwork specification. Screen printing often uses separate solid colours. Embroidery translates shapes into stitches and needs stronger lines with less tiny detail. Laser engraving usually creates a single-colour result influenced by the material underneath. Full-colour transfer or direct digital print can reproduce gradients and photographs, but the surface and colour of the product still affect the final appearance. There is no single file setup that is ideal for every process.
Resolution should be checked at final size. A photograph described as 300 dots per inch may be suitable when printed at ten centimetres wide but inadequate if stretched across a large banner. Image-editing software can show the effective resolution without resampling. If the original is too small, returning to the source photograph or choosing a different image is usually better than applying aggressive sharpening. AI enlargement may disguise pixelation, yet it can also invent edges, alter lettering and introduce strange texture. Any enhanced file needs close inspection at 100 per cent and on a physical proof.
Colour requires realistic expectations. Most screens use RGB light, while common print workflows use inks or spot colours with a smaller reproducible range. Brilliant blues, greens and oranges can appear more muted in print. A defined brand palette helps, especially when it includes CMYK values and named spot colours rather than relying on a visual sample from a monitor. Even then, the same ink can look different on white paper, natural cotton and coloured plastic. For colour-critical work, request a production sample and approve it under ordinary lighting as well as bright studio light.
Fine detail is a common source of failure. Thin lines, small counters inside letters and closely spaced elements may merge during printing or embroidery. The minimum safe line weight depends on the method and material, so follow the supplier’s specification rather than guessing. Create a simplified small-format version of an intricate logo if necessary. It is better to remove a delicate strapline deliberately than to let it become unreadable. View the artwork at actual print size, then step back. If the identity depends on zooming in, it is not ready for the object.
Fonts should be converted to outlines in the final production file so that characters do not change when the printer opens it without the same typeface installed. Keep an editable master with live text for future changes. Check spelling before outlining and review punctuation, dates, phone numbers and web addresses separately. For longer text, ask whether it belongs on the product at all. A concise mark is more likely to remain legible and attractive. Essential instructions may be better placed on packaging or an accompanying card where there is enough room to read them comfortably.
Bleed, safe areas and print boundaries matter whenever artwork reaches an edge or sits within a defined panel. Bleed extends colour beyond the final trim so tiny cutting variations do not leave an unwanted white line. A safe area keeps text and logos away from edges, seams, handles and curves. Product templates should be used at their supplied scale and not redrawn from a screenshot. If a mock-up wraps flat artwork around a three-dimensional object, inspect likely distortion and decide which angle matters most when the item is used.
File organisation can prevent expensive mistakes. Give each approved version a clear name that includes the product, colour and version number. Package linked images where required, remove hidden alternatives from production pages and state which artwork is final in writing. Supply a visual reference alongside the production file so the printer can quickly spot a missing element or wrong colourway. Keep approval emails and proofs together. When several teams are involved, one person should own the final sign-off rather than allowing contradictory edits to arrive from different directions.
Finally, treat proofs as a production checkpoint rather than a formality. A digital proof confirms layout, spelling, dimensions and placement, but it cannot always represent surface colour, texture or scale accurately. Measure the indicated print area on a real object if possible. For a large or high-value order, a physical pre-production sample can justify the extra time and cost. Crisp Gopromotional printing begins long before the press starts. With suitable source files, method-aware design and careful approval, the finished object can preserve the clarity and character that made the original artwork effective.
