Print guidelines & finishing
Print Guideline
![DPI-Print Guideline Icon]()
What's the best resolution to print in?
We print at 200dpi, which is a good combination of quality and file weight. Ideally, your image should be scaled to 100% at 200dpi, this means that no resizing of your file occurs stopping any interpolation.
![Jpeg-Tiff Print Guideline Icon]()
Should I save my file as a TIFF or JPEG?
For multi-coloured or very detailed files we recommend using a tiff format, but they must be flattened. For simple colours and low detail files, a jpeg is fine.
![RGB-CMYK Print Guideline Icon]()
Which colour model should I choose? RGB or CMYK?
We advise providing images in the RGB colour space. Specifically using the sRGB image profile, to achieve best colour results. What does this mean? In your editing software choose RGB as the working space, and assign the image profile as sRGB (full name sRGB IEC61966-2.1)
![GSM ICON]()
What does GSM mean?
Grams per Square Meter (GSM) is an international standard for measuring the weight of paper or fabric. GSM uses the weight of a square meter (1000 x 1000mm) as an indication of the weight and thickness of a given fabric. We class 20-100gsm as light (summer fabrics, gauzes and fine silks), 101-249 gsm as medium (most clothing fabrics) and 250+ gsm as heavy (upholstery fabrics, and other specialist fabrics).
![Fill Bleed Areas ICON]()
What are the bleed areas?
When designing your product, it’s best to make sure that your image is slightly larger than needed. In printing, the extra printed image is referred to as a “Bleed Area” or margin, and it is removed from the finished piece. A bleed area acts as a buffer for slight inconsistencies in the manufacturing process. however, it’s important to fill your bleed areas completely, or you may end up with white, unprinted strips along the edge of your finished product.
![Transfer-Print Guideline Icon]()
Do you print on garments a customer supplies?
Unfortunately not. All our garments are printed on flat fabric and sewn into finished products, which gives a better, finished result and all-over print. We test meticulously so that we know what gets the best results on our fabrics, and our facilities cater perfectly to them. We do however print sublimation paper to order, so if you have access to a heat press you can press your fabrics or flat garments easily.
![Pattern Alignment Across Seams ICON]()
Can you Align a Pattern or design across panels of a garment?
We always strive for the greatest accuracy when printing and constructing your garments. However, due to unavoidable stretch or movement of the fabric during the stitching process, we cannot guarantee perfect pattern registration across garment seams. We are generally accurate within 2-3mm, which Is close enough for most patterns but may show slight issues with detailed geometric patterns.
![print label option icon]()
Can I print my own Labels?
Most of our garments now come with printable label space for you to add your own company information and branding! If you would like to sew in your own labels, we also offer Printed Fabric Labels here.
![Eco friendly Printing]()
How is your fabric printing eco-friendly?
With environmental consciousness in mind, our fabrics are all printed using completely water-based inks. This means no chemicals or solvents are used. Our heat fixing procedure fixes the colours and prints, avoiding the downsides of steaming, such as excess or contaminated water returning into the waste system. We have one facility in London where we conduct all the printing, production and fulfillment.
