Hybrid silk screen and direct-to-garment printing machine and process
A hybrid printing machine is described having both silk screening stations and a direct-to-garment digital printing station with a raster image processor to control a portion of a printing process.
1. A hybrid digital and screen printing system comprising:
an endless conveyor;
a direct-to-garment (DTG) printing station positioned proximate the conveyor and having a print head moveable into a printing zone, the printing zone having a length dimension and a first width dimension and the print head mounted for movement exclusively along the length dimension of the printing zone;
a direct to screen (DTS) printing machine for preparing a silk screen for use in the DTG printing station; and
a raster image processor (RIP) electronically coupled to the DTG printing station and the DTS printing machine, the RIP having a processor, and a memory storing computer-readable instructions.
2. The hybrid digital and screen printing system of claim 1 wherein when the computer-readable instructions are executed by the processor it takes the following steps:
store in the memory a digital art file containing an electronic representation of the colors and their locations to be printed on the substrate to produce an indicia;
sending a first signal to the DTS printing machine representative of a base coat of the indicia; and
sending a second signal to the at least one DTG printing station representative of the cyan, magenta, yellow, and black colors of the indicia.
3. The hybrid digital and screen printing system of claim 1 wherein the print head has a plurality of print heads positioned in an array of rows and columns.
4. The hybrid digital and screen printing system of claim 3 wherein there are from 1 to 10 print heads in each row.
5. The hybrid digital and screen printing system of claim 4 wherein there are from 4 to 20 print heads in each column.
6. The hybrid digital and screen printing system of claim 4 wherein each row is dedicated to a single color.
7. The hybrid digital and screen printing system of claim 6 wherein the rows follow in an order of cyan, magenta, yellow, and black.
8. The hybrid digital and screen printing system of claim 4 wherein a first row will have n number of print heads and an adjacent row will have n-x number of print heads where x is from 1 to 3 print heads.
9. A hybrid digital and screen printing system comprising:
a direct-to-garment (DTG) printing station having a print head moveable into a printing zone, the printing zone having a length dimension and a first width dimension and the print head mounted for movement exclusively along the length dimension of the printing zone;
a direct to screen (DTS) printing machine for preparing a silk screen for use in the DTG printing station; and
a raster image processor (RIP) electronically coupled to the DTG printing station and the DTS printing machine, the RIP having a processor, and a memory storing computer-readable instructions.
10. The hybrid digital and screen printing system of claim 9 wherein when the computer-readable instructions are executed by the processor it takes the following steps:
store in the memory a digital art file containing an electronic representation of the colors and their locations to be printed on the substrate to produce an indicia;
sending a first signal to the DTS printing machine representative of a base coat of the indicia; and
sending a second signal to the at least one DTG printing station representative of the cyan, magenta, yellow, and black colors of the indicia.
11. The hybrid digital and screen printing system of claim 10 wherein the print head has a plurality of print heads positioned in an array of rows and columns.
12. The hybrid digital and screen printing system of claim 11 wherein there are from 1 to 10 print heads in each row.
13. The hybrid digital and screen printing system of claim 12 wherein there are from 4 to 20 print heads in each column.
14. The hybrid digital and screen printing system of claim 12 wherein each row is dedicated to a single color.
15. The hybrid digital and screen printing system of claim 14 wherein the rows follow in an order of cyan, magenta, yellow, and black.
16. The hybrid digital and screen printing system of claim 12 wherein a first row will have n number of print heads and an adjacent row will have n-x number of print heads where x is from 1 to 3 print heads.
