UK Knitwear Design and Sampling

At Jack Masters, our team's primary goal is to make your product vision a reality.

The first step in this process is design and sampling. 

We take great pride in the close working relationships that we build with our customers and we believe that good communication is the key to making this process as quick and easy as possible.

Along with our UK based in-house designers, or with a spec that you supply, we will develop your prototype lifecycle. In close consultation with our highly skilled Design and Development team we will ensure your garment is produced using the right materials and trims to make your style a bestseller.

Drawing from years of experience and know-how as a world leader in fashion technology, Japanese knitting machine specialists, Shima Seiki, have created a design workstation that goes far beyond the simple patterning & programming. With powerful proprietary hardware and industry specific software developed in-house, no other knitwear design system even comes close to SHIMA-APEX System.

Using APEX, our highly skilled technicians can quickly produce 3D-knitting simulations and machine programmes, to help you to achieve the look you require, enabling a faster design to production to store service.
