Welcome again! In part one in every rubber stamps of this 3-element series, the benefits and drawbacks of laser-engraved rubber stamps have been discussed. In the first article you found that despite the fact that laser engraving has a excessive begin-up cost, its satisfactory and performance are second to none. In this segment, you’ll study the advantages and fallbacks of a photoengraving stamp-making technique.
Making a rubber stamp thru a chemical or photopolymer system may also require sizable begin-up charges. Depending on the system skills, quality, or length, a photopolymer stamp-making package may cost everywhere from $400-$4000. This technique calls for a giant quantity of labor and tends to have a better turnaround time than the laser-engraving method.
The first step of the photopolymer method involves creating a negative of the image to be engraved. To start, create or gain a very black graphic on a totally white heritage. If the picture has colours, shop or convert it to a monochrome or -bit format. A simple graphics editor, such as Paint (which automatically comes with a Windows working machine) will allow the user to “Save As” and choose a “Save as type” as “Monochrome Bitmap.” This will convert the colored photograph right into a black-and-white bitmap record. Once the photo is absolutely black and white, the usage of a portraits editor (once more, Paint will work), invert the colors. This will create a white photo on a black heritage.
Turnaround time for a rubber stamp will range substantially, as this variable is contingent on the advent of a metallic plate. If you’re developing stamps for a laugh, you’ll want to have enough pix to fill each a metallic plate and a matrix (mold) board. The metallic plate and matrix board can be made on a partial board; however, this isn’t always an green use of materials and can make for choppy molds and/or stamps. If maximum efficiency is desired, sufficient graphics will need to be received to create a complete metallic plate. Additionally, the photopolymer system does not allow small companies to make custom rubber stamps efficiently, as these rubber stamps tend to be made for a one-time order and the mold is no longer needed after its preliminary use.
Depending on the materials to hand, the metal plate may additionally need to be made by way of an engraving company. Once the metallic region has been engraved, it’s far positioned in a device with the matrix board and, with a combination of warmth and strain referred to as vulcanization, the matrix board is made right into a mold. The rubber is cut to the scale of the mould, positioned inside the vulcanizer, and creates a rubber stamp thru a comparable procedure of warmth and stress. Be warned: as a mold is placed beneath heat and pressure every time a rubber stamp is created, it can handiest ultimate for forty-60 stamp vulcanizations.
After the rubber has been pressed, it may be reduce into individual stamps. As the rubber is quite thick, most stamp enthusiasts agree regular scissors aren’t enough. Kai Scissors are considered an important device in the arts and crafts international. These scissors can be located at crafts shops or on the internet, and Kai Scissors makes 15+ styles and sizes of scissors. Mounting foam is also needed to ensure the block the stamp is mounted on does now not are available contact with the floor to be stamped. Once the rubber and mounting foam have been reduce, the stamps are glued to a timber mount and are equipped to electrify!
We have mentioned laser engraving, photoengraving, and one last stamp-making technique is yet to return! Next, learn how to make rubber stamps, without any special or expensive system, from the privacy of your own home!
