What’s the difference between SCADA and HMI?

March 25, 2019 | Daywey Chen

Industry 4.0 is about the connection and communication between machines and systems to ultimately reach decision making with the absence of a human. More and more data are gathered throughout the production process. The machines get smarter with the increasing amount of data to work with. As a result, the production process becomes more efficient and productive and less wasteful. The ideal situation is to form a network of these machines that are digitally connected with one another to create and share information that results in the full power of Industry 4.0

In today’s competitive environment, printers need to be as competitive as possible. To be competitive, one needs to choose the right tool for the right job. Wide web flexo press and narrow web flexo press both has its advantages and disadvantages. At the end of the day, it comes down to what your main goal is. For instance, is your main goal to be as environmentally friendly as possible to save cost from pollution emission and to build up a good eco- friendly company image? Is your main goal speed since most of your job orders are very long runs? Is your main goal for printing labels at small quantity?

Eliminate the Dangers of Steel with TruPoint® Doctor Blades

October 19, 2018 | Christine Duggan

This week KYMC invited Flexo Concepts to share about press room improvement from a doctor blade standpoint. Every industry has its challenges, and for the flexo printing industry, they include anilox scoring and pressroom injuries related to the use of steel doctor blades. Fortunately, due to advancements in polymer materials and tip designs, press operators no longer have to trade the safety benefits of plastic doctor blades for the effectiveness of steel...

Water based ink V.S Solvent based ink

September 28, 2018 | Daywey Chen

Typically speaking water-based ink could be considered if your application is to run at slower printing speed and on an absorbent substrate. The water-based ink that consists of much less organic solvent could provide printers with less VOC emission issues to worry about. At KYMC we had a customer that ran solely on water-based ink as VOC emission permits are required in the region. As the sales orders fluctuate from month to month, the VOC emission permit may be insufficient or excessive depending on the order quantity of that month. To avoid this issue...

AM Screening V.S FM Screening

August 30, 2018 | Daywey Chen

Must Know Screening Concepts to Succeed in Flexo Printing

AM screening and FM screening both has its advantages and disadvantages. In general FM screening are more suitable for details images, highlights, and shadows. AM screening performs better in mid-tones. FM are more consistent in its ink delivery, therefore, some say that it is able to produce a very stable appearance. This could be good things unless your print doesn’t match your proof. When the mismatch occurs, it will be difficult for press operators to tweak the appearance on the press. As Technologies advances, the newer XM screening takes advantage of AM & FM screening to produce to better print quality.

Rotogravure V.S. Flexographic – Cost Analysis

July 20, 2018 | Daywey Chen

As the flexible packaging industry evolves and as environmental awareness surges, the printing methodologies change. In the flexible packaging industry, the flexographic process is widely adopted in the west and are starting to spread in the east. Below we compare the cost of the two processes from a few perspectives: printing operation, equipment investment, printing plate storage investment and printing plate cost, lifespan and lead time.

Flexographic Plate – Photopolymer or Elastomer?

April 20, 2018 | Daywey Chen

At KYMC, we have observed the integration of the elastomer plate and photopolymer plate usage. Taking advantage of each strength. The more durable and seamless attributes of the elastomer plate are used for printing repeated background designs. The fragmented designs and designs that require many versions are printed using photopolymer plates.
