Flexographic printing has many joining processes, such as screen printing, bumping, die-cutting, etc., and the integration of each process into flexo joining is a satisfying and winning process.
Flexo printing is a circular and circular printing principle, relief printing and relief printing.Intaglio is a pattern module made of copper that is set on a metal roller.Letterpress printing is divided into two parts, a metal lightweight roller and a resin plate.The resin plate needs to be pasted at the position corresponding to each gravure plate.It's difficult to paste them accurately.Letterpress printing has a relatively small texture and can be easily crushed.Therefore, the supplier made two positioning holes in the embossing plate when making the printing plate.The plate is held in place by two locating pins.The resin sheet is attached to the roller with double-sided tape and finished.In the pasting, it was found that the gravure printing plate and the relief plate had many embossed holes.The best way is to move the embossing position so that it matches the gravure so that a set of stickers has to be placed.There are a lot of patterns that are unclear when the startup operation hasn't happened for several hours.When I stopped, I saw the letterpress was shattered.Because the pattern is more subtle and can easily break the grain if barred, you'll need to change the letterpress.
If you want to attach a relief version, you have to think about how to stick the relief printing better and faster.First, place the double-sided tape on the resin board, then remove the back side of the layered paper over the double-sided tape.The front is the first one.If this is the case, the plate will not stick to the drum.Splurge freely.Then match the text on the letterpress to the text on the intaglio, print the letterpress on the intaglio by hand, replace the plate rollers so that they move to the position of force, remove the handle, and apply appropriate pressure.Then I took all the missing files and I didn't lose it.I put the whole version on Metal Roll and the whole version was even posted.If that's not the case, see how it goes.For example, if the letterpress is too low and the demand moves a little, the version will pick up from below, bend upward, and the balance will be held.Then attach to the drum.Then I picked up the plate from above and found the position of the crooked man.I pulled it up slightly and slid it onto the rollers.should be no problem.In the second production, according to this method, there was no crushing, but there was a new problem: the double-sided tape was not pressure-resistant, and the double-sided tape under the letters was left open for several hours and was crushed, and the lines Not clear.At first, I thought about replacing it with white cardboard.First I lost the double sided tape underneath the pattern, then cut the white cardboard into the shape of the double sided tape and attached the white cardboard with glue.Just like put the version on top.Treat the slurry and then talk briefly about pressure and unevenness.There are three ways to do this:
1. The pressure on the base itself is unevenly adjusted.When pressure is applied manually, the intensity is different on both sides and the pressure is uneven.At this time, the pressure on both sides can be completely lost, and the intensity can be mastered until it is suitable;
2. When filling white cardboard, the thickness of the white cardboard that can be selected is different, and the white cardboard should be changed.
3. The resin board itself may have quality problems.When inspecting the material, sometimes the quality of the board cannot be identified with the naked eye, but the hand touch can also be felt through the touch pad.If the pressure after applying the board is very light, depending on the size of the pressure, a thick and appropriate layer of tape can be applied to the surface of the resin board, and the pressure is not light.However, if the pressure is high, then choose another version.
