When a t shirt printed with plastisol ink is not cured properly, the printed image on the garment will break down very quickly during washing. While start up businesses may choose to use flash cure units to do the final cure of the print initially, it is important to realise that doing this should be a short term measure. Also keep in mind that there are certain limitations when using a flash cure unit to complete the final stage of curing. The first such limitation is that you should only cure smaller images in this way and certainly not a printed image on the garment that reaches the limits of the spot curers size. It is also best not to try to dry very large solid areas of print with only a flash dryer. As a specialist manufacturer of screen printing dryers, presses and spot cure units, the Vastex range offer exceptional value for money. The Vastex range offer various models and within the range you will find tunnel dryers that are ideal for drying products such as plastisol printed t shirts, water based inks and discharge inks. The range of infra red tunnel dryers offer plenty of choice and scope for growth as most models are upgradeable. We are able to offer solutions for the entry level t shirt printer all the way up to high production shops thanks to the variety of models and options.

In printing, anilox1 is a method used to provide a measured amount of ink to a flexoprinting plate. An anilox roll is a hard cylinder, usually constructed of a steel or aluminum core which is coated by an industrial ceramic whose surface contains millions of very fine dimples, known as cells. Depending on the detail of the images to be printed, the press operator will select an anilox roll with a higher or lower line screen. Low line screen rolls are used where a heavy layer of ink is desired, such as in heavy block lettering. Higher line screens produce finer details and are used in four color process work such as reproducing photographs.

Experienced press operators are skilled at determining the appropriate rolls for a given print job. Depending on the design of the printing press, the anilox roll is either semi submerged in the ink fountain, or comes into contact with a so called metering roller, which is semi submerged in the ink fountain. In either instance, a thick layer of typically viscous ink is deposited on the roller. A doctor blade is used to shave excess ink from the surface leaving just the measured amount of ink in the cells. The roll then rotates to contact with the flexographic printing plate which receives the ink from the cells for transfer to the printed material. Anilox roll selection should be based on cell volume or capacity of the engraved cells. Print results are accomplished with this volume, which transfers to the printing plate and then to the substrate.

Screen printing is a printing technique whereby a mesh is used to transfer ink onto a substrate, except in areas made impermeable to the ink by a blocking stencil.

In general transfer efficiency is approximately 2. Cell count remains the same for the life of the roll while volume changes over time due to wear, plugging and damage. Cell count accommodates volume at various cell shapes available from the laser engraving process. The same cell count can be engraved to or wear to different volumes. Contemporary ink metering systems employ a self contained system known as a chambered doctor blade system which is basically a manifold which delivers ink to the anilox roll. Ink is pumped through a hoses to the chamber which fills to capacity. Ink is retained within the system by end seals and doctor blades. One blade work as a retaining blade, simply holding ink within the chamber. The other reverse angle blade works as previously described, removing excess ink from the engraved surface of the anilox roll. Chambered doctor blade systems are recognized for high quality, consistency and accuracy removing the influence of press speed and some human subjectivity. Roll manufacture and specificationeditAnilox rolls were originally made using a process of mechanical engraving, utilizing hardened steel tools of various cell counts and cell shapes diamondpecking machine, but modern rolls are laser engraved. Screen Printing Today Pdf' title='Screen Printing Today Pdf' />The characteristics of an anilox roll determine the amount of ink that will be transferred to the plate angle of the cells, cell volume, and line screen. A 6. 0 degree angle ensures maximum density in a given space. Lower volume makes for less ink. Low line numbers will allow for a heavy layer of ink to be printed, whereas high line numbers will permit finer detail in printing. Both cell volume and line screen are closely correlated. The rolls are often specified by their line screen2, which is the number of cells per linear inch. These often range from around 2. Most rolls sold are within 8. LPI, although a spike in demand for those with 8. Anilox rolls are almost always designed to be removed from the press for cleaning and for swapping out with different line screen rolls. See above Anilox rolls are properly specified by cell volume for the required print application. How to Print Screen on a Mac. Also wrong the PrintScreen key is not a Microsoft convention.

Higher volumes address combination, screens, line work, solid coverage and coating applications. In virtually all printing applications with various print requirements, one volume will not print all to the highest quality. Limited print stations generally call for a compromise between the highest quality graphics and color. There are many variables to consider when specifying an anilox roll beyond the print requirements, such as substrate, ink system, plate material, plate mounting tape, press speed, drying capacity., etc. Best course of action is to consult suppliers of all these components for proper engraving specifications from their experience. Anilox roll specifications  Line Count or Transfer VolumeeditThere are four ways to specify Anilox rolls settings. Based on transfer volume, based on line count, American standard and European standard. Transfer VolumeeditThe European standard for transfer volume is cmm or cubic centimetre per square meter which means how much volume cm of ink will be transferred on how much surface m of paper. Sometimes, ink suppliers will give a recommended transfer weight per square meter, expressed in gm. In which case you need to know the ink density before converting gm to cmm. The American standard for transfer volume is BCM in also written BCMsq in or BCM, which means billion cubic microns per square inch. Cubic microns m is a unit of volume and one billion cubic micron 1 0. So 1 BCMin 1. Line CounteditLine count3 will measure the finesse of the pattern on the Anilox roll. It measures how many cells are engraved per centimetre or per inch. In Europe the standard is LPCM or lines per centimetre. In America, the standard is LPI or lines per inch. The conversion from transfer volume to line count isnt straightforward. Because depending on the pattern used for the cell and depth of gravure of the anilox roll, the cell might contain higher or lower volumes of ink. So the only way to convert cmm transfer volume to LPCM cell finesse or BCM to LPI is to look at the conversion chart provided by the anilox roll supplier. Frutiger Lt Font more. Also, any given anilox roll will age after some time and its actual transfer volume will be less and less. Handling and maintenanceeditThough large wide web flexo rolls are only maneuverable by overhead crane, on smaller presses anilox rolls are often handled directly by operators. Extreme caution must be taken when handling these pieces of hardware as a single bump against a hard surface or sharp corner can destroy the delicate cell structure on the surface and render a roller completely useless, at a cost of around US5. Nicks and scratches add up quickly, so fine brushes never brass brushes are used for cleaning the anilox roll. Anilox rollers that are used with water, solvent and oil based inks, which dry when left sitting out and unagitated, must be cleaned immediately after use or a problem known as plugging occurs, where minuscule amounts of ink dry in the cells. This leaves tiny, but unacceptable, pinholes in anything printed from the roll in the future. Hanna Hi 9828 Manual. ReferenceseditExternal linksedit.
