FAQs for paper and ink (II)

is FM plus worth the investment

answer: many printing plants have begun to try to use FM or other optional addition methods. Compared with traditional printing, the new addition method makes the printing positioning registration easier and the color reproduction more stable. It is used in various large buildings with bright colors and higher saturation, and a small point can also save 20% of the ink

however, there are exceptions. If the designated substrate is kraft paper or a rough surface, the traditional screen 150 to 175 lines can still achieve better results. The dot enlargement of traditional screen on uncoated paper is small

should we invest in soft proofing or Remote Proofing

answer: for different applications, soft proofing and Remote Proofing have different positions. They are the best way to simplify the proofing process, and the quality of these systems is significantly improved, but they are not ideal for every customer or job. These new technologies are more suitable for blue proofing or urgent work, and this proofing method is often not used for color correction

the effect of Remote Proofing with color management is much better, which can establish a closer relationship between designers and printers. Everyone involved must adopt the agreed operating system, output system (printer calibration), paper and ink settings, display correction and other factors that affect the color

for those users whose jobs are not very different, it is worth spending time, money and efforts to establish a remote proofing system

if successful proofing technology is adopted, does the designer still need to check before printing

answer: This is a hot topic at a recent printing customer seminar. Only a few designers and printing customers only rely on samples for confirmation. After all, they hope that the quality of each page is intact

since it is impossible for designers to leave the sample viewing of the printing workshop, they should seize every opportunity to train them. A recent study by Manroland showed, "what is checked on the printing press?" Ranked second among all the topics that designers most want to know, you may wonder why so many designers and printing customers want to know what they need to check when they finally print on the machine? How many measures can be taken at this time? If customers pay attention to your work, your observation and heart will also be greatly improved

does synthetic paper printing need special consideration

answer: synthetic paper printing is not much different from traditional paper printing. It can also be embossed, bronzed, die cut and other treatments. Because of their super smooth surface, the printing contrast of these papers is the largest, and the paper will be very smooth. If your customer wants the product to have a long service life, it is recommended to use synthetic paper in the fixture to prevent the specimen from slipping and breaking. They are durable and scratch resistant and do not break when folded

although synthetic paper is suitable for the standard offset printing process, additional attention needs to be paid to the choice of ink. Work closely with ink suppliers. The ink used must be very suitable for paper. The low solvent ink has bright colors, and the printing quality of sheet fed printing is also very stable

because synthetic paper is non porous, it requires a long drying time and additional control of the printing fountain solution, because excess water may interfere with the transmission of ink

aqueous and UV glazing can give special protection to printed matter. Yupo company, the world's largest manufacturer of synthetic paper, suggests that when it is necessary to polish synthetic paper, avoid going deep into the production line 1 of the enterprise to investigate and study the following pigments: Red Lake C, reflective blue, purple, violet and rose red, which may fade. Ink suppliers can substitute these pigments

does it overestimate the good side

answer: there are obviously many problems in the promising paper market. Some paper mills continue to produce whiter and brighter paper, which is easy to cover up some problems: does the paper work well on the printing machine? Is opacity suitable for printed matter? At the same time, is there a problem with the grade of paper

when the American forest and automatic paper detection Association (Washington, D.C.) classifies paper, it is divided only according to the brightness of the paper. We know that the brightness of No. 2 paper should be 83% to 84.9%, which is why the brightness of No. 3 paper exceeds 90%. In other words, brightness is no longer the only focus of attention, and the grade is ultimately determined by the market

a very bright paper usually costs more. Fillers and chemicals, such as phosphors and brighteners, are necessary to increase the surface luminosity of the paper. They provide a blue white effect for the paper, and can also transmit the stability of the paper and the paper routing of the web. This is the additional service you get when you buy No. 1 paper: brightness and certainty provide the paper with good paper routing of the web

final tips
