Ink manufacturers rely on their vehicle and varnish suppliers to help provide the critical characteristics that printers seek, whether it is resistance properties, color, gloss, drying speed or countless other properties. Vehicles and varnishes help ensure the final printed product meets the necessary requirements.
Ink companies continue to seek new products with even more enhanced properties, but these come at a cost, considering increases in raw material prices. Vehicle and varnish manufacturers are balancing these new requirements as well as pressures on profitability.
‘Guts’ of the Ink
When it comes to the performance of an ink, vehicles and varnishes play a critical role.
“Polymers enhance the color, stability, gloss, drying speed, resolubility and resistance properties of an ink or coating,” said Rick Krause, business manager for BASF Resins. “They are the ‘guts’ of what holds inks or coatings together. Ink and coating companies capitalize upon their formulating expertise to achieve the right balance of properties and applied cost based upon the portfolio of polymer products we offer.”
“They are the primary building blocks of the ink that determine the ink’s overall performance probably more than any other component, pigment and color notwithstanding,” said Guy Trerotola, market manager, commercial offset for Hexion Specialty Chemicals.
“Oil-based vehicles influence the viscosity, set speed, film hardness, transfer, emulsification properties and other on- and off-press characteristics of printing inks,” added Carol Durgan, tactical marketing manager, Noveon Resins & Polymers. “Ink companies look for gloss, heat resistance, product resistance, rub resistance and other end use properties to enhance and protect packaging.”
“Ink varnishes are ‘vehicles’ for a reason; the vehicle is what conveys the pigment to the printed page,” said Art Lersch, president of Alvar. “Also, the vehicle is the ink component most responsible for the final properties of the printed film. Ink vehicles are the heart of the ink.”
Vehicles and varnishes ultimately play a key role in how well the ink runs on press.
“Most importantly, our customers want better runnability, water balance and trouble-free press runs,” said Dan Delegge, Inksolutions’ vice president, smoke ‘n’ mirrors. “Vehicles and varnishes can promote these qualities.”
“Today’s printers put more demand on ink makers than ever before,” added Jerry Trauth, lab manager, Kustom Group. “Vehicles are the highest percentage raw material in an ink formula, and therefore control most of the physical and application properties. So the pressure is always on the vehicle manufacturer to push the limits of existing technology.”
Vehicle and varnish suppliers are being counted upon to help their customers.
“New products are only one part of the puzzle,” Mr. Trauth noted. “Just as importantly, ink manufacturers expect their vehicle supplier to have product in stock when they need it, and in the right container. They expect you to carry both their high volume products and their one drum a month product. Ink makers expect a technical partner who is an accessible resource they can tap when needed, for formulation or press side assistance, and regulatory or FDA compliance issues. As a vehicle supplier, it’s our responsibility to meet these requirements.”
Mr. Delegge said developing specialty products is proving to be a successful approach.
“The single biggest trend we see is the movement toward specialty products, such as unique overprints, adhesion to plastic, hybrid inks or others, all of which we like to focus on,” said Mr. Delegge.
Mr. Delegge also noted that there are a number of startup ink companies entering the market. “New starter companies are having an impact on us,” Mr. Delegge said.
Vehicles and varnishes can make a major difference in the ink, and that provides significant value.
“Cost effectiveness is what ink and coating companies and their customers continue to seek, but it goes beyond the ‘cost per pound’ trap that so many companies fall into,” said Mr. Krause. “Providing a differentiated product that provides in-use value to reduce the total system cost is what companies really need. Tell me how I can sell more value through better product performance; tell me how I can more cost-effectively service and supply my customer – these are the questions we hear from our customers. We continue to invest in new product development to address enhanced product performance; improved health, handling and regulatory considerations; and effective formulated cost-in-use.”
“Vehicles produce inks that are more forgiving and provide consistent performance under all press conditions, a good value proposition that combines optimum performance with acceptable economics,” Mr. Trerotola added. “Ink makers are not necessarily seeking the least expensive vehicles. Rather, they want vehicles that offer value through trouble-free ink performance, a quantifiable reduction in waste and that make it possible to produce high quality inks that will command a favorable overall return to the ink maker.”
“Every ink company wants to use quality vehicles that deliver good press and finished print properties, and price is always important,” said Mr. Lersch. “At this time, there is a lot of interest in high solids vehicles with fast setting. This is the case in both sheetfed and heatset vehicles. People, especially from the EU, are inquiring about petroleum oil-free formulations.”
There is always going to be a continuous demand for higher-quality vehicles and varnishes.
“Trying to maintain costs while improving product performance is a concern,” Mr. Delegge said. “It’s OK to get performance, but you have to provide value.”
As is the case for virtually every ink ingredient supplier, vehicle and varnish manufacturers continued to face higher prices for raw materials during the past year.
“Oil-based products continued to increase in 2006,” Ms. Durgan said. “All raw materials were impacted by the increase of shipping and transportation costs resulting from increasing oil prices.”
“Raw material prices went up, and so did the price of ink vehicles, driven primarily by higher prices for resins, ink oils and drying oils such as soy and linseed,” Mr. Delegge noted.
“There appears to be more stability in most petrochemical-based raw materials in Q1 2007 than there was in 2006,” Mr. Trerotola said. “Rosin and rosin derivatives are still tight and continue to command peak price levels.”
“Raw material prices rose very significantly in 2006,” Mr. Lersch noted. “It was one of those years when everything was up, oil prices, natural gas prices and both synthetic and agriculturally-derived chemicals. Virtually everything used in printing ink starts from one of those sources. With everything going up at once, there is nowhere to hide increases in costs and we had to adjust our prices accordingly.”
Margins continued to suffer, as manufacturers are unable to completely pass along these higher costs.
“2006 brought a degree of cost stability compared to the dramatic industry-wide increases observed in 2004 and 2005,” Mr. Krause said. “Yet, pressures on profitability remain significant throughout the ink industry and with their raw material suppliers. No company has been able to pass on the entire amount of cost increases – everyone is sharing the pain. If global economic growth continues to be healthy throughout 2007, basic feedstock costs are unlikely to ease. Profitability will continue to be a challenge for the industry in 2007 and beyond.”
There have been some interesting changes in the marketplace. For example, the smaller vehicle and varnish manufacturers have been actively extending their operations. Inksolutions is expanding its Westcoast Inksolutions operations, moving into a new building in the Los Angeles area and adding new equipment to service customers. Kustom Group completed its facility expansion during the second half of 2006, which included increased manufacturing to three shifts.
On the M&A front, Akzo Nobel Resins was acquired by Hexion Specialty Chemicals, while BASF acquired Johnson Polymers, forming BASF Resins.
“2007 will be an exciting year for BASF Resins,” Mr. Krause said. “We expect to introduce a number of new water-based polymer products this year. We will be relocating to our new commercial and technical headquarters in Wyandotte, MI. And we’re learning more about the variety of products, chemistries, and technologies within BASF that we hope to share with the graphic arts marketplace.”
The Coming Year
Vehicle and varnish makers say they anticipate good results in 2007. For example, Mr. Trerotola anticipates continued market contraction in North America and less volatility in the raw material market.
“Economic forecasts continue to point to an easing of growth for the U.S. economy,” Mr. Krause said. “We’re expecting our business to continue to grow steadily throughout 2007.”
“Noveon expects 2007 to be a good year for our vehicle and varnish areas,” Ms. Durgan said. “However, this will most definitely be a result of the continuation of hard work from both our commercial and technical teams, who keep our customers’ needs as a top priority.”
