A Guide To T-Shirt Printing Colour Separation

1. A Guide To T-Shirt Printing Colour Separation The traditional screen printing method of printing on t-shirts can be a challenging process. Various approaches are available when it comes to screen printing. However, colour separation is the major factor you must consider during t-shirt printing. What is colour separation? To put it simply, colour separation is the process of identifying various composite colours before printing. It is mostly used for printing multi-colour images. ● Colour separation happens when pre-press firms employ different screens for each colour to print real-life or vector images. ● Before printing a full-colour image, businesses divide each colour into the four primary hues of Cyan, Magenta, Yellow, and Black (CMYK).

2. ● Then, they separate screen plates for colour blending. ● Lastly, each colour is printed individually on top of the other to get high-quality print on a plain t-shirt. It is possible to blend almost unlimited colours using CMYK screen plates. Types of colour separation 1. Spot colour separation The most popular and fundamental method of colour separation is spot colour separation. It is utilised when the artwork is created using solid, non-gradient colours. However, spot colour separations, though usually solid, may use some halftone dots to add shade. CorelDRAW, Adobe Photoshop, or Illustrator are typically used to generate spot colour separations. The best aspect of this type of t-shirt printing online is that there is no overlap between colours. Also, they all fit snugly and neatly next to one another. 2. Four-colour or process colour separation Cyan, magenta, yellow, and black (CMYK) halftone dots are used in the four-colour process to produce finely detailed, lifelike pictures. Process separations function remarkably effectively with white T-shirts but poorly with dark T-shirts. This is because the process inks are somewhat transparent, which means that a t-shirt with a dark colour will show through the ink printed on it. 3. Simulated process printing Halftone dots are used in simulated-process colour separations, much like in four-colour process separations, to produce detailed pictures. Simulated process colour separations differ in that they employ a variety of ink colours.

3. As it creates vibrant, vivid colours independent of the t-shirt colour, this is a superior alternative for complicated, tonally rich wholesale t-shirt printing. 4. Index colour separation Index colour separations provide colour shading by using square pixels of the same size instead of halftone dots. The tiny squares are printed close to one another, unlike simulated or process printing. You, therefore, get a "jigsaw" effect with tone fluctuations. The image looks tonal and varied since the human eye typically cannot recognise this effect. This method is easier to execute than process separations. However, producing a photorealistic print sometimes requires using additional colours. The bottom line! Each of the four colour separation techniques has a specific use case. ● Four-colour process: Mainly utilised for photorealistic photographs on light-coloured plain t-shirts ● Index colour: Generally used on textiles and requires more shades than simulated or process colour ● Spot colour: Mostly utilised in high-quality process prints ● Simulated process: Mostly utilised for deeper photorealistic photos Even though various screen printers will have their own preferences for colour separations, if you identify and stick with a technique that works for you, you can boost the success rate of your separations.
