Pre-Registering Print Cylinders On Press, Malcolm G. Keif Jan 2008

Pre-Registering Print Cylinders On Press, Malcolm G. Keif

Graphic Communication

Those who study lean manufacturing know that waste comes in many forms. We must remind ourselves that anything that does not produce exactly what the customer values, when it is needed, is a wasteful operation. Makereadies, or press setups, are wasteful, at least in the eyes of our customers. Reducing press setup time is critical for improving customer value and making the printer more competitive on short-runs while increasing overall productivity. Even though make-ready time is built into an estimate, the bottom line is that it isn’t something a customer is delighted about paying for. Reducing makeready time, therefore, becomes …


Making Superior Plates Every Time, Malcolm G. Keif Jan 2008

Making Superior Plates Every Time, Malcolm G. Keif

Graphic Communication

Flexo plates are a critical component of the printing system. Printing is a system—viewing platemaking in isolation doesn’t address the total print process. A system has multiple components that interact with each other and influence the performance of each. Great plates with the wrong anilox rolls offer nothing to improve quality. Likewise, great plates made from a poorly prepared file help little to produce an outstanding final product. So, looking upstream and downstream is necessary to ensure your plates are supporting the total printing system. Superior printing plates… •have sufficient resolution for the graphics to be reproduced on the substrate …

A Study Of Pla Printability With Flexography, Xiaoying Rong, Malcolm Keif Mar 2007

A Study Of Pla Printability With Flexography, Xiaoying Rong, Malcolm Keif

Graphic Communication

Most products are boxes, bottles and bags. The printability of biodegradable film has not been fully investigated. This study tested the printability on clear and white Polylactic acid (PLA) films, and compared the print qualities to common packaging films like Polypropylene (PP), Polyethylene terephthalate (PET). Water-based flexo ink was used to test printability on PLA films. The influence of anilox roll and plate screen ruling was also considered. The print qualities were reported as dot shape, tone reproduction, and mottle. This study showed that biodegradable films could achieve similar quality compared to common packaging films. While printed at different screen …


The Study Of Missing Dots Of Electromechanical And Laser Engraved Cylinders, Xiaoying Rong, Alexandra Pekarovicova Mar 2007

The Study Of Missing Dots Of Electromechanical And Laser Engraved Cylinders, Xiaoying Rong, Alexandra Pekarovicova

Graphic Communication

According to the previous study, the printability of electromechanical engraved cylinder and laser engraved cylinder were different in terms of density, tone reproduction and mottle. In this study, the missing dots of two different engraved cell types were investigated. It showed that different cell structures had strong effect to ink transferring and the characteristics of missing dots. Lasers engraved cells were less affected by ESA (electrostatic assist). When there was no ESA applied, the laser engraved cells showed less missing dot area, which indicated better ink release from spherical shaped cells. ESA had more effects to coated substrates than supercalendered …

Cost-Estimating For Commercial Digital Printing, Malcolm G. Keif

Graphic Communication

The purpose of this study is to document current cost-estimating practices used in commercial digital printing. A research study was conducted to determine the use of cost-estimating in commercial digital printing companies. This study answers the questions: 1) What methods are currently being used to estimate digital printing? 2) What is the relationship between estimating and pricing digital printing? 3) To what extent, if at all, do digital printers use full-absorption, all-inclusive hourly rates for estimating? Three different digital printing models were identified: 1) Traditional print providers, who supplement their offset presswork with digital printing for short-run color and versioned …


Why Lean Isn't Working In The Print Industry, And What You Should Be Doing About It!, Malcolm G. Keif, Kevin Cooper Jan 2007

Why Lean Isn't Working In The Print Industry, And What You Should Be Doing About It!, Malcolm G. Keif, Kevin Cooper

Graphic Communication

Change does not come easily for the print industry. Actually, strike that. Change does not come easily for most industries. There are a wide variety of reasons why people, companies, and industries do not embrace change. Without a willingness to change, companies get stuck in patterns that prevent them from not only progressing operationally, but also culturally.

Why Aren't We Leaner In The United States?, Malcolm Keif Nov 2006

Why Aren't We Leaner In The United States?, Malcolm Keif

Graphic Communication

Lean manufacturing has certainly been a hot topic lately for flexo printers and converters. It is rare to attend a conference or look through a trade magazine without seeing the subject as a central focus. Lean seems mysterious, almost Zen-like, partly because we use Japanese terms like muda, kanban, and kaizen instead of just using English translations. For many, we are just getting familiar with the concepts of Lean. Waste identification and reduction are certainly primary themes. Just-in-Time, 5S, Small-lot Production, and Setup Reduction are all recognizable Lean components. Some have seen improvements in their costs and efficiency, but others …

Identifying High-Volume Printing Processes, Malcolm G. Keif, Tom Goglio

Graphic Communication

Printing professionals frequently examine printing to see how pieces were produced. They break out loupes and look at the dots. Is it offset or gravure? How about flexo? It is important to be able to distinguish among printing processes through examination in order to determine the key variables to control for quality printing. Further, expertise is established and confidence built when a professional can determine how something is printed.


Gravure Printability From Laser And Electromechanically Engraved Cylinder, Xiaoying Rong, Jan Pekarovic, Alexandra Pekarovicova Oct 2004

Gravure Printability From Laser And Electromechanically Engraved Cylinder, Xiaoying Rong, Jan Pekarovic, Alexandra Pekarovicova

Graphic Communication

Gravure printability comparison of laser engraved and electromechanically engraved cylinders was done on five different substrates. Ink transfer was less reduced on laser print than electromechnaical when printed without electrostatic assist. Print mottle was significantly lower and yellow, magenta and black laser engraved images, while cyan print from laser engraved cylinder had higher mottle on some substrates (SCB, SCA and freesheet). Overall, the print quality than that from the electromechanically engraved one.
