Pass This term refers to the amount of passes that the print head is required to make for the optimal color application. In single-pass modes, the nozzles spray using the whole width of the print head. The rule-of-thumb is: the lower the pass mode, the bigger the print span per head pass. The higher the pass mode, the more times the printer head must go back and forth in order to achieve the desired resolution. This is because in high passes, not all nozzles are active, but rather only one part. This way the printed area is generally more homogenous.
Perforated Sheet Perforated films are mainly used for frontal stickers on glass surfaces. Typical examples of use are public transport, cars or building advertisements (here above all shop design). The perforation proportion of LG films can be selected at 30% or 50%. As the reverse side of the film is dark grey, the unobstructed view from inside to outside is not impaired.
Permanent Adhesive A film and/or its adhesive is described as permanent if removal over the shelf-life period is not possible without leaving behind remnants of the adhesive.
Piezo InkJet Piezo ink jet describes a print method in which an electrical pulse causes a metal membrane to vibrate. In doing so, the ink is ejected from the ink cartridge through mechanical acceleration. As the ink is not heated, as is the case with the thermal ink jet method, this method is gentler on the printer head.
Pigmented Ink If the printed graphics are to be used outdoors, pigmented inks are recommended. They offer high color stability. Unlike dye-based inks, the pigments do not dissolve in the liquid, but remain solid. In general, the color space represented by pigment inks is smaller than the dye-based inks. The shortage is already offset in many printers thanks to additional color stations.
Pigments Color pigments determine the hue of the film. Pigments must fulfill the high requirements regarding color and light fastness as well as withstand high service temperatures and production temperatures. Pigments are produced from organic and inorganic materials.
Polymer Films The quality of the softening agent used and the proper combination of the type of softening agent has a considerable influence on the quality of a film. Here the polymer softening agents are generally more stable than monomer softening agents when under stress, such as high temperatures. Film with a higher quality softening agent also has a longer life span. Monomer calendered films are normally guaranteed over a usage period of 2-3 years, while polymer calendered films can be used for a period of approximately 5-6 years.
Pre-separation The term pre-separation describes the installation of foil letters and/or logos plotted by way of transfer tape to self-adhesive labels.
Protective Laminate Protective laminate is essentially a transparent film which is laminated on to the printed film to protect it against harmful UV rays and mechanical stresses. Normally the lamination happens with a cold laminator. Protective laminates are also available in different degrees of shine (glossy, matt).
Protective Paper

The protective paper on the films has several important functions in the processing of the films.

 It protects the adhesive from contamination, enables the film to remain flat during treatment, intercepts climate related variations in moisture and guarantees easy removal of the film even following a long storage period. Furthermore it guarantees the grip of the films in plotting as well as the bonding of application tapes on optional scripts.


Large print runs of writing, logos and cut-outs with complicated cutting edges are produced most efficiently through punching. This is suitable for finely adjustable flat presses such as, e.g. cutting plates with an automatic hand feeding device. Kiss-cutting refers to the cutting and/or division of film and adhesive from the protective paper in the manufacturing of logos, letters, emblems, etc.

A logo is already set by the cutting press so that the film letters remain pre-separated on the protective paper after the retraction of the waste gate.

Quick Ageing Test Using a convection oven heated to approximately 300°C, different criteria can be reviewed (e.g. the bonding to critical backgrounds such as polyethylene or polycarbonate, the gas emission on critical backgrounds, such as glass fiber reinforced plastic or the shrinking tendencies at different temperatures.
Removable Adhesive Removable means a clean removability of the film over the specified shelf-life period.
Removal of Protective Paper Lay the film on a flat, clean background, with the protective paper facing upwards. The film should now be unfixed at one corner and peeled off smoothly, as is necessary for further bonding steps. When removing the protective paper, ensure that it peels off cleanly and does not cause any folds or creases in the film. Therefore, the protective paper should always be removed from the film and not the film from the protective paper.
Repositionable Adhesive To avoid initial bonding, some films from LG Hausys include sliding-glue properties. The films display their optimal bonding strength only after at least 4kg of pressure has been applied using a squeegee. Only after this does the full effect of the bonding strength come to effect. The advantage of this is that small corrections to the bonding can be made immediately, without damaging the film. Only after the film has been optimally bonded, is the final position fixed using the corresponding squeegee pressure.
RGB This abbreviation stands for the primary colors of the color system, namely red, green and blue. The color white is the result of overlapping the three primary colors or addition. Therefore, one also talks about the additive color mixture when talking about RGB.
Rivet Brush When bonding metal surfaces with small rivets, it is recommended that a rivet brush is used in order to fully bond the film to the surface. For this the film is initially bonded as a bubble on the rivet. After the rivet heads are located, the film should be punctured with an adhesion pin to release any air. Then firm pressure is applied to the film using a rivet brush and a heat gun.
