    The Importance of Appearance and Rising Standards

    We had an interesting thing happen a couple of years ago. A major Tier 1 Automotive Supplier, (we’ll refer to as T1), contacted us to see if we could help. Their customer, a top selling luxury car manufacturer, was raising the specifications on their paint finish and T1 was being asked to match. T1 told us that they could meet the new specifications but not consistently. They were hoping we could help. Fortunately, we had a champion at the T1 plant that was familiar with us and with work we had done in other finishing operations.

    Where Do You Control Material Temperature?

    We are fortunate to get the opportunity to tour many manufacturing plants and review a large variety of dispensing processes. One thing that really stands out is that most companies do a good job dispensing. Whether it’s a manual dispensing operation with skilled and experienced operators or an automated dispense with highly repeatable motions, in general, the companies we see are already doing a good job.
    When we’re out there, we often hear that either the booth or the plant are already temperature controlled. Often, this is said as if it eliminates the requirement for material temperature control. While definitely an improvement over no control, simply controlling the temperature of your booth and your plant, may not be enough to accomplish your quality and cost objectives.

    When it comes to flexographic printing, maintaining consistent quality is paramount to the success of your operation — and profitability.

    Yet riding that thin line of consistency is easier said than done, as any number of issues can crop up in your process.

    However, every issue has a solution.

    Here are four common problems that can occur with your ink, including known causes and how you can potentially correct each one.

    Norcross has been in the viscosity control business for over 80 years. During that time we have seen “best practices” in the industry come and go. Some have become the standard and some have been displaced by new practices or technologies.

    10 Signs You Are Having Viscosity Related Problems

    Even in the best circumstances, (new gearless high speed presses, highly trained and attentive pressmen, atmospherically controlled environments, great ink suppliers, etc.), you can still have print issues.

    Many of those issues may be related to ineffective viscosity measurement and control.

    New Growth Demands Higher Quality for Corrugated Packaging and Printing

    Posted by Mark Portelli

    Feb 1, 2018 12:57:00 PM

    Since 1871, corrugated has been a staple of the packaging industry — and the larger U.S. economy. In fact, the global market for corrugated box packaging is forecasted to hit $307.9 billion in 2025, growing at 4.6 percent each year until then.

    For printers, this represents the potential for a lot of new business. But every opportunity comes with challenges.

    So, what do printers need to know to take full advantage of this expanding market?

    Demand for higher quality packaging

    For corrugated printers, the key trend is rising demand for higher quality packaging. According to Technavio, “a developed and mature U.S. market” is driving demand for premium consumer products — and thus also higher quality packaging. Technavio explains:

    “Premium packaging is a basic indication of the high quality of the product inside. Vendors use expensive ingredients, technologies, colors, and other raw materials to develop premium packs. Many consumers also buy these products as gifts, thereby driving the demand for premium packaging in the market.”

    Small corrugated boxes with high quality printed designs are also often used in retail stores near, around, and in checkout lanes, says Technavio:

    “Retail giants such as Walmart are using this form of packaging in the premium brand segment to improve marketing activities. These boxes are placed at the point of sale to attract consumers.”

    This begs the question: how can corrugated printers prepare to provide these more premium designs?

    It’s all about consistency…

    Meeting the demand for higher quality packaging is no simple task. Even the smallest printing imperfections can lead to rejections — and a reduction in profitability.

    This means that corrugated printers need to be on high alert and watch out for issues such as:

    • Improper or inconsistent color
    • Dot bridging or feathering
    • Bleeding
    • Fisheyes
    • Halos

    Manual adjustments to correct such issues are costly — and they create the opportunity for even more problems. This can leave corrugated printers between a rock and a hard place.

    But there’s good news.

    Ink control automation eliminates the need for manual adjustments. With automation, printers no longer need to worry about the careful balance of viscosity, pH, temperature, and evaporation. Ink control handles it all, making worry over ink management a thing of the past!
