Jacquard Repeat Length Priced as Card Time and Loom Hours
Pricing Jacquard repeat length requires balancing flat card preparation fees against loom hour rate increases caused by harness mass speed penalties.
EJC File Compilation
Digital Instruction
Assembly of electronic data files containing the patterns and machine settings for computerized jacquard looms facilitates the production of complex linen designs. Successful EJC file compilation requires the conversion of artistic designs into technical instructions that the loom’s controller can interpret. The file dictates the lifting sequence of every individual warp yarn to create the intended motif in the fabric.
Pattern Coding
Technicians translate the interlacing structure and the colour arrangement into a digital format compatible with the equipment. During the EJC file compilation, the software checks for mechanical errors such as long floats that would make the linen fabric unstable. The density of the picks and the tension parameters are also embedded within the data package.
Once the file is ready, it is transferred to the loom via a local network or a secure storage device.
Production Readiness
Verification of the file accuracy before the loom starts prevents the waste of expensive flax yarn. If the EJC file compilation is flawed, the interlaced pattern will show irregularities or the machinery may suffer a mechanical collision. Mill managers archive these files to ensure that repeat orders of the same linen design are identical.
Accurate data management is the foundation of digital cloth production.
