16 BASIC PRINCIPLES OF OPERA TION Note: The MT Ink Roll is disposable by design and is not to be used with the 4 oz. ink cartridge. When the ink is depleted from the MT Ink rolls they are to be discarded. NON-POROUS INKING SYSTEM Inks designed for printing on non-porous surfaces contain very fast drying alcohol solvents, a component to impart color[...]

17 BASIC PRINCIPLES OF OPERA TION It is also extremely important to test the affect of other manufacturer ’s ink on the XF Neoprene ink roll. Since the ink roll must fit into a precision machined cavity in the inking system housing with little clearance, swelling of the roll, in reaction to non-compatible solvents in the ink, could cause serious [...]

18 BASIC PRINCIPLES OF OPERA TION When the coder is installed on a Form and Fill machine, the plastic film may move at fairly high speed when pulled from the supply roll but it stops for a period of time during the product fill cycle. In these applications, if the die face has already rotated passed the T ransfer Roll and picked up ink and the web [...]

19 WEB PRINTING T o eliminate this problem, if idler roller positions are not adjustable, a slight undercut in the face of idler roller “B” where the printed marks pass under the roll, will prevent the wet marks from touching the face of the idler . Generally the undercut in the idler roller needs to be only .020" - .030" deep and sli[...]

20 WEB PRINTING 3 -Press down lightly on the spring tension arm to compress the tension spring slightly . (Fig- ure 35) While holding a light pressure on the arm, tighten the mounting bracket clamping screw . Note: This procedure is used to adjust the contact pressure which the print drum exerts against the web. Only enough pressure should be appli[...]

21 WEB PRINTING Universal Non-Porous Conveyor Line Printers can also be mounted on custom designed extension arms which will enable them to print directly on the surface of a master roll of web material as it is unwound. This technique is fre- quently used when conveniently positioned idler rolls are not available. In these applications, as the mas[...]

22 WEB PRINTING In web printing applications where multiple coders are required to be mounted across the web, Universal offers special mounting hardware which facilitates gang mounting the coders as indicated in Figure 38. In these instal- lations, special CLP-SBA Saddle Mount Bracket Assemblies are used in conjunction with an extruded structural a[...]

23 CART ON PRINTING Universal Non-Porous Conveyor Line Printers are spring loaded so that the print drums will press against the carton surface on contact. This pressure is necessary to accomplish the friction drive rotation of the print drum and ensure enough printing pressure to give you a sharp impression. The spring tension mechanism on the cod[...]

24 CART ON PRINTING Before tightening the mounting bolts, check alignment of the print drum. It is very important for proper tracking that the top of the print drum is parallel to the top of the conveyor (Figure 41) and the side of the print drum is parallel to the side of the carton (Figure 42). Once this alignment has been achieved, tighten the m[...]

25 CART ON PRINTING Figure 45 illustrates the best die position for carton printing when using extremely fast drying inks. Note that the leading edge of the printing die should be positioned rotationally upstream of the transfer roll. When the leading edge of the carton contacts the print drum, the drum begins to rotate in a clockwise direction. Th[...]

26 CARTON PRINTING If the cycle rate of the production line is very fast and the ambient temperature is relatively low , the printing dies could be positioned rotationally downstream of the transfer roll so they print much closer to the leading edge of the carton. When the coder completes one printing cycle, a portion of the die or all of the die m[...]

27 MAINTENANCE 3 - Inspect the roll to ensure it is completely saturated with ink but not dripping wet. If the surface of the roll seems excessively wet after inking, remove the excess ink by in- serting a rod through the core and while pressing down lightly , roll the roller across a clean piece of paper . PRE-INKING A NEW INK ROLL When you are re[...]

28 MAINTENANCE 1 - Periodically , the inking system should be disas- sembled and inspected for ink residue and dust con- t amination. T o remove ink cont amination from the surface of the machine, moisten a soft cotton cloth with the appropriate ink solvent and rub it across the contaminated area. CLEANING THE TRANSFER ROLL The surface of the trans[...]

29 MAINTENANCE 3 - Blot the surface of the die with a clean paper towel to dry as shown in and reinst all the clean dies on the coder . CLEANING THE PRINTING DIES All inks which are formulated for printing on non-porous surfaces contain a resin binder which bonds the dye or pigment in the ink to the surface of the material being printed. As the ink[...]

30 MAINTENANCE Mounting configuration conversion involves the “mirror image” reversal of the pivot arm assembly that holds the inking system and the tension arm assembly which provides the printing pressure. Indexing printers require the additional reversal of the index ramp and repositioning of the index ring. Universal Non-Porous CLP Coders a[...]
