PRINT HIGH / Flexografi

Flexografi Print is a printing technique that uses a reference printing plate of rubber or Photopolymer. Print Flexografi also known as high print because of a higher score than a part that does not print. Including high technique is letterpress printing, rubber reference plate with a higher hardness than Flexografi plate. As for hot stamping, which is also a letterpress printing plate using tin as a hardcopy reference. In Flexografi printing, transfer printing ink to the plate through the transfer roller is made of Anilox and copper (Cu) or ceramic. Flexo Print simple understanding we can see the process of how to seal the paper to print pictures.
Flexo printing productivity is high enough at around 1-5 million tracks with a variety of materials such as paper, plastic, foil, cardboard boxes, and others. This printing technique is also often used to print a wave cardboard (corrugated), labels and flexible packaging.

How a print Flexografi
Flexografi work process, menggunaka rotary printing system and direct, where there is ink on the plate will directly dicetakkan to material to be printed. Protruding surface printing is the opposite of the system where the surface of gravure printing enter. Printing plates mounted on plate cylinder predetermined width and length (repeat length).
Ink settings here using Anilox roll, which will be selected according to the type cetakkannya and rasternya subtlety. Doctor blade and used to flatten the ink attached to the Anilox roll, because photopolymer plates made of highly elastic, then the printing Flexo printing pressure must be a minimum of termed a kiss impression. This function to avoid the occurrence of dot gain is very large which can interfere with the printout.
Anilox Roll is a roller that serves to transfer the ink from the inkwell to the plate. This material is made of copper or ceramic. Because the ink transfer function, then these components must be able to move the ink as much as possible toward the printing plates. For this purpose, the anilox surface must have a very good density and the right raster form.

Flexo CTP
In line with the progress of laser technology and applied, it was getting Flexografi positive impact of technological development was the discovery of Computer to Plate (CTP) Flexo.
This machine does not differ greatly with Offset CTP. Recording system using internal or external types of drums. Heating the lower surface of the plate is also going on in this Flexo CTP. Flexo CTP is the emergence of a superior Flexogrfi separate from the print, which rasternya better than using film. Dot gain can be minimized and the impact on the print quality is good also.
With this tool the precast process can be shortened because the digital data directly from the design to the reference dioutput through photopolymer printing Flexo CTP.
Print advantage Flexografi:

# Can print on materials that easily absorb the ink and does not absorb, such as paper, cardboard and plastic.
# Can use water base ink, solvent and UV base.
# The photopolymer plates can print up millions of impressions.
# With the anilox roll, not much needed adjustments as in the offset ink.
# Can print motif uninterrupted (continuous), such as gift wrapping, wall paper and others.
# It can be done on-line hot stamping, die cutting, embossing and screen printing.
# Can print to a continuous roll of labels so that the machine supports the work in automatic.
Flexografi print Disadvantages:
# Konsitensi color tends to vary, especially in water and solvent based ink, while the UV ink is very stable.
# Dot gain is high enough print

Not imagine when we buy something, especially food items or drugs but no labels? Especially in the hospital, medicine bottles there is no label, then certainly the patient can die more quickly because it could be one of injectors.
Another term of the label is a sticker. To create a label with a small amount we can use the printer at home with stickers and paper cut by hand, machines and even digital printing is also fully equipped for label printing needs but the number and shape are still limited. But what if we want to create a label with the number of 2 million Exemplar? And shape but the box is not diverse? Of course the solution we have to go to print labels.

Data from the designers of the CD / Flashdisk, received and analyzed by the precast and prepared in accordance with the requirements (trapping, print signs, step and repeat, etc.) after Ok, then become a reference dioutput through the photopolymer film (manual) or Flexo CTP. Having completed the benchmark in the printing stage using Flexo printing machine rotary. Results to be printed in the form of rolls and then roll in Finishing as needed (diecutting, slitting, etc.) and checked the quality of printing by the new QC sent to the client.
In the manufacture of labels, used printing machines do not have one type of machine but can also be combined with lainnyaseperti printing screen printing, holograms, hot print, and others according to demand and design of the client.
