I talk with sign and digital print for pay companies everyday, and there seems to be one common thread: everyone wants to make their eco solvent printers more profitable. There are loads of different settings and adjustments to optimize the performance of their printer. I came across an article in the August 2008 issue of Sign Business Magazine and think you'll walk away with some great insight.

There are a few things you can do to get the best image quality out of your printer. Many of these tips are mentioned in your user’s manual that no one ever reads! A refresher could help many of us. Before you start, it’s important to make sure your printer is firing all of its nozzles. Perform a test print in the morning before production to ensure and maintain print quality. Perform a cleaning cycle until it clears all misfiring printheads. Check your user’s manual to see how to do this function.

Heaters are used in solvent printing to assist with the curing and adhesion of the ink. Because we’re using (in most cases) uncoated media, we have no way to control how much each drop of ink will wick or bleed into each other. Too much ink and the images will look grainy and textured. Not to mention the risk of media reaction to this heat, which may cause it to buckle and cause damage to your printheads. On the other hand you must be careful to make sure the temperatures are not too low or the ink will bleed and look blurry. To make sure you have proper temperature, start off with a temp around 40-45 degrees Celsius and slowly raise the temp until you get a crisp test pattern. Note: Some media will have a thicker backing, which serves to insulate the media from heaters.

Head height is commonly overlooked feature by many users. To start, it can help you to get crisper edges on your prints, and in many cases, eliminate overspray issues. Print heads require a certain distance from the media to get optimal print quality. If your print head height is set too high, you get blurry, misaligned images. Too low and you risk having your print heads strike the media or excessive back spray buildup. Both of which can easily call for replacing a print head. To avoid these problems, most printers have at least 2 head height positions (Low and High). The most important thing to remember is if you are using such materials as adhesive backed vinyl or paper, then you want to use the lower position. If you are running thick banner or magnetic material you must use the highest head settings. Important note: Make sure to check your head height before printing. This will not only assure good print quality, but you prevent unnecessary overspray or head strikes, which can reduce maintenance costs.

Feed correction: On many Roland printers this is called print adjust. Feed correction is designed to make sure that there is minimal banding when you use different thickness of material. How far the feed motor feeds the material is determined by this calibration. Without it, you could spend all day playing with other settings trying to get more consistent output and end up frustrated. Some printers print small blocks on top of each other and depending on the distance between these blocks, you make adjustments in the feed distance. If the blocks overlap, then you need to increase the feed distance with a positive value or in case of gaps in the blocks, you decrease the distance with a negative value until you can see little or no seam between the patterns.

Software: Software can cause all sorts of headaches if you don’t have it sorted out. Remember that the software almost always overrides the hardware settings. If you change your feed and heater settings all configured on the printer, but fail to check the settings in the RIP, it is possible to print your work using all the wrong settings. Most RIP’s will have an option to turn the control over these setting on or off. As a general rule, I recommend that you change your settings in either the RIP or on the printer and never deviate. Especially if more than one person operates the printer.

These steps are simple and easy to remember. Just a few minutes each day before you begin printing is all it takes to assure quality images. At CAD Supplies Specialty we strive to arm our customers with the knowledge necessary to make sure your production environment is a stress free as possible. Please call our Service department with any questions or concerns.

 So Long Dog Days of Summer!

My favorite time of year is upon us. Not only have my favored Longhorns started a new season, we are also on the home stretch of the year. Everyone is back from summer vacations and buckling back down to work.

I had hoped to talk about the many different projects going on here at CAD Supplies Specialty, Inc., but we are not quite ready for prime time. We are beginning to update and improve our web site; a major undertaking I can assure you. There has been a loud cry to incorporate an online ordering system. Definitely exciting, but hard to pull off!! We may even be able to institute a tracking system that will update our clients when they need supplies! Pretty exciting stuff, but takes a while for the programmers to figure it out.

We are starting on the 2008 CAD Supplies Holiday Calendar. We hope it continues to be a big success! We’ll be pounding the streets over Christmas Holidays with calendars in hand.

If this was not ambitious enough, we hope to further expand into San Antonio. We are working now to build our support staff. We now have a full-time graphics technician and software specialist. We now service HP Designjets, Solvents, Seiko LED’s and Roland Solvent printers. We hope to add Epson service in the near future.

With all the projects in the planning stage, we’ll stay busy all through the New Year! I have already warned my wife to hold dinner. As always, we greatly appreciate the support from our great clients. Keep up the good work. I’ll let you know as the web site and online ordering becomes a reality.

Are you feeling the earth shake and hearing a loud roar? Are you reading bylines like ""Major Again" or "Will Muschamp Defend?" Overhear names like Colt and Chiles, or Oklahoma, #$@!^-$#? Yes, Texas football is here, again!

So when you 'steer' yourself to The Stadium for a tailgate party and a game, enjoy some bar-b-que, beer, fun & friends, and take some of these historical facts and figures to amuse them all!

The first University of Texas-owned football field -- called the Varsity Athletic Field -- was constructed in 1897 for a total price of $3,000. It was renamed Clark Field, in honor of George B. Clark, who had many roles at UT during his tenure. It was the only football and track field until the construction of Texas Memorial Stadium in 1924.

In 1923, Henry Jacob Lutcher Stark, chairman of the UT Board of Regents and L. Theo Bellmont (the west side of the stadium is named in his honor), then UT athletic director, along with thirty student leaders began an ambitious plan to build a concrete stadium to replace the Clark Field. In the following year, completion of "the largest sports facility of its kind in the Southwest" was crowned with a 27,000-seat facility, designed by architect Herbert M. Greene of Dallas, the total cost came to $275,000, financed with support from an estimated 10,000 students, friends, and UT alumni.

The student body dedicated the stadium, Texas Memorial Stadium, in honor of the 198,520 Texans, 5,280 of whom lost their lives, who fought in World War I. Just two years later, with the growing popularity of football all over the country, Texas Memorial Stadium was enlarged with the addition of a 13,500-seat "horseshoe" on the north end of the complex. Its main entrance bore a striking resemblance to the façade of the Alamo. Again, in 1948, expansion included seats enclosing the north end raising seating capacity to more than 60,000.

The Longhorn football program began to distinguish itself under head coach Darrell K. Royal, the first UT coach to capture a national championship in 1963. In 1969, work began on the west–side upper deck, by then the stadium held a whopping 75,504 seats. In a TCU-Texas game that year, Texas Memorial Stadium was rededicated to the memory of all alumni in all American wars.

The University honored legendary football coach Darrell Royal, who led Texas to three national championships and eleven Southwest Conference titles, by officially naming the stadium after him in 1996, Darrell K. Royal - Texas Memorial Stadium.

GodzillatronOne of the hallmarks of the current UT stadium is its audio/visual centerpiece, nicknamed, "Godzillatron", in the south end zone. The $8 million high-definition display board is 55 feet high by 134 feet wide, providing live and recorded video, scores and stats, graphics, animation, and sponsor advertising.

Just to add a not-so-short note on "Naming Rights". Did you know that the Texas football team plays on the Joe Jamail Field, along the L.Theo Bellmont West Side of the Darrell K. Royal-Texas Memorial Stadium, beside the Frank Denius Athletics Fields practice complex, as well as a new 1,200 seat Red and Charline McCombs Softball Field and Mike A. Myers Track and Soccer Stadium next to the FEDCU Disch-Falk Field for baseball, (take a breath!), and they train in the Moncrief-Neuhaus Athletic Center!!! How about a CAD Supplies Specialty Goal Post?

Endzone RenditionIn 2006 UT Regents approved a $179 million expansion plan, to include a new memorial plaza and north end zone structure. Scheduled to be completed by the first game of this 2008 season, the outdoor plaza will serve as a memorial to veterans and will also include a multi-level complex with an upper deck, club space, suites, athletic offices, and a basement with gym space. Our client, Michael Minor of Rago Ltd. Construction, tells us they are on schedule! Seating will increase to over 90,000, until the "final phase" of expansion, with the construction of permanent seating and an upper deck in the south end zone completely enclosing the playing field. The stadium capacity could reach 118,000 with that completion. No timeline has been officially announced for this portion of the project.

DKR-TMSAs always, Come Early, Wear Orange, Be Loud, & Stay Late!

By the way, in 1924, Texas lost the first game to Baylor 28-10, attendance was 13,500, then defeated Texas A&M 7-0 in the dedication game on Thanksgiving Day with the attendance at 35,000! The first night game was a loss to Texas Tech 20-14 on September 17, 1955, attendance had grown to 47,000.
