A decal is an adhesive product that can be used for information or decoration purposes. It is referred to as a sticker, label or nameplate. Decals are made using a printer or a vinyl machine. They vary based on the application used in the printing process. Depending on the quantity of decals and where you require the decal design to be printed, offset, laser and screen printing machines can be used to print your decals.
Offset Printing Machines
Due to industry improvements in paper, inks, and plates, offset printing became the popular form of commercial printing in the 1950s. Such improvements allowed for greater speed and plate durability. Offset printing machines contribute to about 40 percent of printing worldwide. When compared with digital printing, offset printing has higher set-up costs but is cheaper to produce. Printing higher volumes reduces the price per unit. Also known as lithographic printing, offset printing provides vivid, sharper images. If you have a large volume of decals to be printed, an offset printing machine is ideal for the job.
Laser Printing Machines
A laser printer is one that utilizes laser beams to produce an image on a drum. The laser’s light alters the electrical charge on the drum wherever it hits. The drum is rolled through toner and the toner is transferred to the paper. Laser printers are also called page printers because an entire page is transmitted to a drum before the toner is applied. These printers are known for their resolution, or the number of dots per inch (dpi). Resolutions range from 300 dpi at the low end to 1,200 dpi at the high end. There are some laser printers that produce higher resolutions. This is called resolution enhancement and involves special techniques. If you are seeking high resolution decals, a laser printer will get the task done.
Screen Printing Machines
Screen printing machines are compatible with a number of surfaces. These include textiles, ceramics, metal, wood, paper, glass, and plastic. These printing machines are considered to be a notch above the rest as they can print on substrates of any shape, thickness and size. Screen printing also allows you to display the stimulating effects of the design on the item you desire to print. These effects are a result of the number of dyes and inks such as solvent, water, solvent plastisol, water plastisol and UV curable which are used during the printing process. Screen printing is the ideal method for printing nameplates, signs, labels, shirts, t-shirts, logos, text or artwork repeatedly on fabric or most flat surfaces. It is also recommended for ceramic decal printing.
