Talk about digital direct printing and digital rotary heat transfer printing
Release Date:31/10/2016
There are two main types of digital printing: digital direct printing, digital rotary heat transfer printing.
1. Digital direct printing is to send the patterns need to be printed into the computer by high-resolution scanners, SLR cameras, or card digital cameras, then print the patterns onto the fabric by digital printers with in-built control software to form the digital patterns, and solid color after printing.
2. Digital roller heat transfer printing, same as digital direct printing, is to send the patterns need to be printed into the computer by high-resolution scanners, SLR cameras, or card digital cameras, then form the patterns by in-built software.The difference is, digital direct printing is to print the ink directly onto the materials, but digital transfer printing is more complicated: to printing the patterns onto the specified papers, dry ( or blow-dry by fan ), then get into transfer printing process by cover the papers on the materials needed to be print, heating and pressurizing, to vaporise the ink to the fabric, to finish the whole printing process, but no solid color necessary afterward.
3.Suited fabric for digital direct printing: in general, any light color ( include white ) is suitable, but some fabrics need pretreatment before printing, aging or washing after printing ( for example, 100% cotton reactive digital printing ), some only just need to be dry to solid color, but the feel is not so good.
4.Suited material for digital transfer printing: chemical fiber knitted fabrics, for example, PE, P/C ( polyester is the best )
5.Strengths and weakness of digital printing
The strengths of the digital printing: Whether it is digital direct printing or digital transfer printing,
After printing the precision is very high ,the image shows fine,having clear architecture and many porting references.Due to its printing way doesn’t need to plate making,it can directly reflects the:fast speed,easy to operate etc.The ink and the printing process,ensure environment protection free from contamination,it’s more suitable for more patterns,more sizes and more colors printing simultaneously(There is no limit to the color and quantity)
The weakness of the digital printing:Because it is not formally recommend domestic new products in recent years,the digital printer,the printer nozzle on the printer,the ink,the paper and some other consumables are very expensive,it’s printing speed is slower than gravure printing,it caused the slow to drop in printing and processing costs.Believe that with the popularity of digital printing’s number and technology ,the problem can be solved finally,and it will not take too long time.
