Abstract
The invention concerns an assembly for printing on a substrate comprising: a camera for recording a reference pattern; a computer connected to said camera to store and modify, if required, data (N) concerning the reference pattern; and a printer whereof at least the print head is controlled by a printer file (FI) generated by the computer. The invention is characterised in that it comprises: means supporting and moving the substrate; means for analysing and comparing a pre-recorded pattern with a pattern located on the substrate, and for adapting or not the data (N) concerning the reference pattern as a result of the comparison; and means for generating a printer file (FI) based on the data whether or not modified.
Claims16
A printing method for printing a flat substrate, for example a fabric, involving particularly:
- pre-recording at least one pattern numerically;
- where appropriate, processing the pattern thus pre-recorded;
- generating a printing file (FI) comprising data relating to the pre-recorded and/or processed pattern and carrying out printing generated directly or indirectly from the printing file;
- continuously or discontinuously identifying at least one pattern of a fabric by relative displacement between said fabric and an image acquisition means;
- comparing the identified pattern in real time with the reference pattern pre-recorded for recognition purposes;
- adapting the pre-recorded reference pattern in line, in order to superpose it on and/or fit it to the identified pattern and generating a printing file (FI);
- and carrying out printing dot by dot, directly or indirectly, according to the printing file.
An assembly for printing on a substrate, comprising:
- a camera for recording a reference pattern;
- a computer connected to said camera, in order to store and, where appropriate, modify data (N) relating to the reference pattern;
- and a printing system, of which at least one head for printing dot by dot is controlled by a printing file (FI) generated by the computer;
- a means for the support and movement of the substrate;
- analysis means in order, on the one hand, to compare a pre-recorded reference pattern in real time with a pattern identified on the substrate and, on the other hand, to adapt or not the data (N) relating to the reference pattern as a function of the result of the comparison;
- and means for generating a printing file (FI) from the data (N) modified or not.
