Laser Papers

Laser transfer papers are specially coated media designed to work with white toner laser printers (such as the Uninet iColor series) for transferring full-colour designs with a white underbase onto fabrics, hard goods, and dark substrates. They serve as the carrier that holds the printed toner layers until pressed onto the target substrate, enabling decoration of cotton, polyester, dark garments, ceramics, and other surfaces that cannot be decorated with sublimation.

Uninet iColor transfer papers on 100% cotton typically require 320–350°F (160–177°C) for 15–20 seconds at firm pressure. Peel temperature (hot or cold) is specified on each paper type — never substitute one peel method for another, as peeling cold-peel paper while warm causes the transfer to lift off the garment with the carrier. Verify settings with the specific iColor paper product data sheet rather than relying on general laser paper guidelines.

Laser transfer papers designed for white toner workflows require a white toner printer (iColor 560, 650, or similar) to produce opaque transfers on dark substrates — standard CMYK laser printers cannot print the white layer essential to these papers' function. Some laser transfer papers are formulated for standard CMYK laser printers for light-fabric applications, but these produce semi-transparent results and are only suitable for white or very light coloured substrates.

Paper wrinkling and jamming are caused by using media that exceeds the printer's specified weight range, feeding from the wrong tray, or paper that has absorbed moisture and lost its flat profile. Always feed specialty laser transfer paper from the manual bypass tray rather than the standard paper cassette. Store paper flat in its original sealed packaging — even a few hours of exposure to high humidity causes curl that leads to feeding problems. Verify the paper weight is within the printer's supported range before loading.

On 100% cotton, quality iColor transfer paper designs typically withstand 25–40 wash cycles before visible cracking or edge lifting. On polyester, durability is similar to cotton at 20–35 cycles, but polyester's smooth fibre surface can cause adhesion to be slightly lower depending on the paper type. Washing inside out in cold water and air drying or low-heat tumble drying extend transfer life on both fibre types significantly compared to hot-water machine washing with high-heat drying.

iColor letter-size transfer papers typically cost $1.20–$2.50 per sheet including toner cost. DTF at the same size costs $0.40–$0.90 per transfer including ink, film, and powder. DTF has a lower material cost per transfer, but iColor requires no powder station or tunnel dryer — workflow simplicity and lower equipment investment can make iColor more cost-effective for shops under 100 pieces per week. Beyond 100 pieces per week, DTF's lower per-unit material cost provides a meaningful margin advantage.

Cold-peel carrier tearing usually occurs when the paper is peeled too quickly or at too sharp an angle. Allow the full recommended cooling time (15–25 seconds minimum) before touching the carrier. Peel at a low angle — nearly parallel to the garment surface — pulling slowly and continuously rather than in a sharp upward motion. If the carrier tears mid-peel, stop completely, allow the transfer to cool another 10 seconds, and resume from the tear point at a lower angle.

iColor UltraBright paper is formulated for maximum colour vibrancy and opacity on dark fabrics, with a thicker toner-reception layer that produces richer colour saturation. Select paper is a standard transfer paper suitable for light and medium-toned fabrics and hard goods where maximum opacity is not critical. For dark and black cotton garments where print brightness is essential, UltraBright is the correct choice. For light shirts, ceramics, and mixed substrate workflows, Select offers equivalent quality at a lower price point.

Laser transfer papers used in white toner workflows are coated paper or polymer-based products that do not contain regulated hazardous substances under normal use conditions. They are not recyclable through standard paper streams due to their polymer coatings — dispose of used transfer carriers in general waste. Check with the paper manufacturer for any specific disposal guidelines if you are processing large volumes that might trigger commercial waste regulations in your province.

Store laser transfer papers sealed in their original packaging with any included desiccant in a climate-controlled room at 65–75°F (18–24°C) and below 50% relative humidity. Never store opened packages near an air conditioner vent, humidifier, or exterior wall in a Canadian winter — condensation and temperature swings are the leading causes of paper curl and feed problems. If you open a partial package, reseal it immediately with tape or transfer remaining sheets to a resealable plastic bag with a silica gel desiccant packet.
