In printing process,pictures printed by fedar sublimation printer sometimes have  problem of shortening or lengthening. So why do these problems occur? How to solve it in fedar sublimation printer printing process?
 
1. Printing surface of fedar sublimation printer will shorten or elongate
 
① Regarding stepping accuracy of fedar sublimation printer, if fedar sublimation printer can adjust "step", you can set it, or perform "compensation setting".
 
②In terms of printing media of fedar sublimation printer, because different materials have different surface roughness, friction coefficient is different, so resistance of material forward is different, and progress is fast or slow, but running speed of car is the same; Therefore, during printing, compensation value needs to be corrected, that is, fedar sublimation printer stepping parameters need to be adjusted according to different materials.
 
2. Solution to problem of shortening or lengthening printing surface of fedar sublimation printer
 
①When designing and outputting image screen, please pay attention to correctness of size. When importing pictures using relevant RIP software, pay attention to keeping original size of image unchanged to avoid actual size of image being changed due to reduction of image size during import and recognition operation.
 
②For users with high size requirements, production process meetings must be held to ensure that production-related links are highly valued. Typesetting file for sublimation printing cannot be too long. Stepping parameters of fedar sublimation printer should be adjusted well, and it should be controlled within three meters.
 
③For small-format advertising posters that need to be die-cut, because customers are extremely sensitive to sizes or patterns, they must be strictly prevented from being elongated or shortened. Correctness of parameters must be tested before production and random inspections must be increased. Do careful inspection, rigorous operation and printing production, as far as possible to reduce irrelevant errors that affect size of fedar sublimation printer's printing output.
