Digi-Print Sub-Block Overview
Offers excellent opacity and colour reproduction whilst also being specifically designed to provide a solid barrier to polyester dye migration, which effectively prevents “bleed through” from sublimated dyes passing through the garment and into the design which can occur during the heat press process. It’s designed to be applied to 100% polyester, as well as polyester blends which makes it great for workwear, sportswear and leisurewear requirements where dye migration may be an issue.
Note: Due to the production process, a 2mm keyline is required around the intended design, although this can be coloured to match closely to the garment. Alternatively, a “bleed edge” can be added if the design allows.
Production Leadtimes: Digi-Print Sub-Block Heat Transfers
Sub-Block custom heat transfers are manufactured in the UK and are usually despatched within TWO working days of confirmation of the artwork and colour references.
For full-colour heat transfers, such as Subli-Blocking UltraColour, requires a line-based vector graphic (usually as an .EPS or .AI file format) with any text saved as outlines, or a raster file that is at least 300dpi (dots per inch) at the size required and produced using CMYK colours. If the design contains fine detail (i.e. less than 2mm in line thickness) a line-based vector graphic would be required to ensure that it’s accurately reproduced.
If you aren’t able to provide the artwork in the correct format, we don’t offer direct recommendations but many of our customers use Net Digitising (https://netdigitizing.co.uk/artwork-services/), Digitising Mart (https://digitisingmart.co.uk/vectorart.php) or David Sharp (https://davidsharp.co.uk/our-services/) to have block-colour designs, and designs with a limited amount of shading, redrawn as line-based vector graphics.

What Are Custom Transfers?
Custom transfers are printed designs for applying to substrates, primarily garments such as t-shirts, hoodies and polo shirts using a heat press machine to bond the custom heat transfer to the fabric.
Custom-made, heat transfers can be applied to almost any type of fabric and offer a wide variety of finishes, including block-colour, plastisol ink-based screen transfers, and full-colour photo-quality DST custom heat transfers. Subli-dye blockers can also be added to reduce the risk of dye migration on fabrics susceptible to it, such as performance polyester.
Why Use Custom Transfers?
Custom transfers are a popular alternative to silk-screen printing as it’s a much more cost-effective method of printing in low quantities and also gives the ability to print on demand as our custom transfers are manufactured so they are ready to be heat pressed straight onto the garment fabric.
