Doming is a finishing process that not only enhances the appearance of printed items by producing a three-dimensional look, but it also makes them more durable. The doming process relies primarily on three components: a dispensing system, resin, and a product with surface tension sufficient enough to accept and control the liquid doming resin during and after application.
To manufacture a suitable screen printed job, a large number of variables, such as mesh selection, frame selection, and EOM, must be controlled. Print conditions such as mesh, frame, and snap-off distance influence dimensional accuracy, an important contributor to print quality.
Dimensional accuracy is less important when printing a single-color job than it is when the application is a multicolor job. However, when embossing and diecutting follow printing, image dimensions become more relevant.
Sublimation is defined as the conversion of a solid to a gas without going through the liquid state. The solid in the case of decorative graphics is sublimation ink that has been printed and dried onto a specially coated transfer paper. Applying the graphic to a substrate by using a heat press at a temperature between 400-425°F causes ink to shift from a solid to a gas and transfer onto any polyester surface.
Avery Dennison (www.averydennison.com) recently announced the addition of Conform Black Chrome to its line of Conform Chrome Accent film. The new film joins Conform Chrome Silver, Gold, and Blue, and Avery says it features a mirror-like finish that creates a high-end look for vehicle wraps. According to the company, Conform Chrome Wrapping Films are ideal for unique features such as side-view mirrors, striping, and door handles. The films feature Avery Dennison’s Easy Apply RS Technology, designed to ease repositioning reduce air bubbles, and minimize installation time.
Vastex International (www.vastex.com) recently debuted the VP-Cruiser, a mobile platen rack for organizing, storing, and relocating screen platens. The company says VP-Cruiser is constructed of heavy-gauge carbon steel with a durable industrial finish, has a wide base with four casters to allow platens to be rolled to screen-printing presses for rapid removal and insertion.
Metallic screen-printing inks are typically formulated using two components: metallic pigment and varnish. They are either sold as separate components or as ready-mixed, one-part products. Pigments start in copper, zinc, or bauxite mines. Harvested ores are atomized in fine specks, ground, polished in mills, and classified according to end usage.
Most film laminators (Figure 1) are so similar in purpose that choosing from the many options and models can be tough. Your best bet is to start by considering the laminator size. In general, it’s best to buy the widest laminator you can afford. A wide laminator will allow you to run narrower products side by side, improve throughput, prevent film waste, and grow into larger, more demanding applications. If space is a concern, some wide-format models feature conservative footprints and are ideal for tight production areas.
LexJet (www.lexjet.com) says its Print-N-Stick Fabric brings true photographic-quality printing to an inkjet-receptive fabric material that's backed with a repositionable and removable adhesive. It combines LexJet's Water-Resistant Satin Cloth and a proprietary adhesive system that’s engineered to allow users to easily apply, reposition, remove, and re-use graphics. According to LexJet, the water-resistant fabric is also easy to finish and won't rip, wrinkle, or stretch during production or installation. The fabric is compatible with aqueous and latex inks.
Mimaki USA (www.mimakiusa.com) recently brought the JV400SUV solvent UV inkjet printer to market, billing it as a revolutionary printer that uses a unique, new ink that combines the flexibility of solvent with the durability of UV. The JV400-130/160SUV prints in four colors (CMYK) at speeds of up to 193 sq ft/hr (18 sq m/hr) in draft mode. During the printing process, the solvent compound is absorbed into the ink-receiving layer of the media, and the pigment is settled on to the media.
Static is the excess or deficit of electrons on a material. Static in screen printing is most often caused by friction, separation, heat change, and improper grounding. Screen-printed products normally experience all of these during handling. Potential results of untreated static energy include ink spidering, sheets sticking together, delivery/stacking difficulty, accumulation of dirt and dust, electric shocks, damage and interference in electronic components, and even fires and explosions.
