3 Today s Presenters Jim Mueller Leibinger Group Vice President Ryan Schuelke Enercon Industries Vice President Sales

4 Presentation Preview Benefits of Digital Ink Jet Printing Improvements in Ink Jet Printing Technology Why some surfaces are difficult to bond with Ink chemistries that overcome adhesion challenges How in-line surface treatment improves adhesion Questions/Answers

5 Benefits of Industrial Ink Jet Printing

6 Benefits of Industrial Ink Jet Printing Digital Print Flexibility Text with fully customizable fonts Barcodes 1D, 2D Datamatrix and QR Code Graphics & Logos Variable data Date, time, shift codes, etc External data - Unique code on each product - Ethernet - Serial - USB Database printing with no external PC or Network

7 Benefits of Industrial Ink Jet Printing Ease of Operation Sealed Nozzle Technology Ready when needed Windows CE interface for simple stand alone touch screen operation or network integration

8 Benefits of Industrial Ink Jet Printing Limited Maintenance No daily, weekly, or monthly cleaning required Printers run unattended for months Preventative Maintenance o Low cost o Easy to perform o Required once or twice per year depending on ink type

9 Benefits of Industrial Ink Jet Printing Economical Use Significantly reduced down time on production line Very efficient hydraulic design for low solvent consumption EcoSolv option reduces solvent consumption up to 50%

10 Why some surfaces are difficult to bond with

11 Common adhesion impediments found on plastic surfaces Low Energy Surface Contamination Limited Bonding Sites Plastic Surface Migrating Additives Hydrophobic

12 How the Forces of Cohesion & Adhesion Effect Wetting Out Low energy, lack of bonding sites, and surface contamination have a negative impact on molecular attraction, causing liquids to fail to wet the surface.

13 How the Forces of Cohesion & Adhesion Effect Wetting Out When you observe a liquid beading up on a surface you are witnessing the forces of cohesion (the property of the liquid s like molecules to remain attracted) being stronger than the forces of adhesion (the property of unlike molecules to attract.)

14 How ink chemistries can sometimes overcome surface adhesion challenges

15 How ink chemistries can sometimes overcome some surface challenges

16 Applications FOOD CANNING INKS EXTRUDED CABLE PIPES & TUBES PRINTING CHEMICAL RESISTANT INKS Retort fade resistant inks Thermochromic inks print black then turn Blue or Red to indicate retort process has been completed PVC Inks formulated to eliminate transfer when coiled HDPE & PP Typically require surface treatment for acceptable durability Isopropyl Alcohol Resistant inks Boeing Certified Skydrol resistant inks for use without overcoat

17 Applications EDIBLE FDA FOOD GRADE INK EXTRUDED RUBBER SECURITY FLUORESCENT INKS Print directly onto porous food products White pigmented ink for Silicon Rubber Orange, Magenta, or UV fluorescent

18 How ink chemistries can sometimes overcome some surface challenges Ink Types Solvent based very fast drying MEK based most flexible used for most applications Ethanol based slower drying typically lower adhesion properties Acetone/Ethanol Mix extremely fast dry times Specialty inks

19 How ink chemistries can sometimes overcome some surface challenges Application Ink Requirements Dye based inks Large number of formulations, low contrast on dark material Soft-Pigmented inks better contrast on dark surfaces run in standard model printers Pigmented High Contrast inks - Good contrast on dark products

20 How ink chemistries can sometimes overcome some surface challenges Specialty Application Ink Requirements PVC no transfer inks UV cured ink Clear UV fluorescent security inks Thermochromic inks Glass inks Glass and Polycarbonate wash off inks

21 How in-line surface treatment enables ink adhesion on difficult surfaces

22 Common adhesion impediments found on plastic surfaces Low Energy Surface Contamination Limited Bonding Sites Plastic Surface Migrating Additives Hydrophobic

23 The transformation of a surface prepared for adhesion High Energy Surface Contamination Eliminated Increased Bonding Sites Plastic Surface Hydrophyllic Migrating Additives

24 What is atmospheric plasma surface treating? plasma : n ; Fourth state of matter, (Solid, Liquid, Gas, Plasma.) Mixture of charged ions & energetic electrons generally in equilibrium. Atmospheric plasma surface treaters generate plasma to impart adhesion promotion onto a wide range of surfaces.

25 Atmospheric Plasma Treatment Promotes Adhesion

26 Atmospheric plasma treatment discharge

27 Typical Treatment Results Material Initial Dyne Level Post Treatment Dyne Level Polyethylene Polypropylene

28 Plasma Treatment Results

29 When to consider surface treatment Unacceptable ink adhesion Unacceptable ink durability Inconsistent ink adhesion Desire to improve quality or output

30 Integrating in-line treatment Fixed Location Treater Head Parts are conveyed, indexed or otherwise presented to the treatment head. Moving Treater Head Head can be indexed or robotically controlled to follow precise treatment patterns.

31 Presentation Review Flexibility and ease of use of ink jet printing Adhesion impediments Ink chemistries for specific applications How plasma treatment improves adhesion
