  Thank you for your question.

  Advantages of flexography

  You can use flexography to print on a wide variety of absorbent and nonabsorbent substrates.

  You can print using resilient rubber or photopolymer image carrier,so that millions of impressions can be made.

  You can print more than 10 colors if you use a multiple print station.

  Flexography uses fast drying inks, which might be solvent based, water based or UV curable.

  Flexography is cost effective and economical.

  Students found that triability, relative advantage, and observability were the main advantages of using flexography

  Flexography is environmentally friendly.

  Flexography involves a simple printing process.

  Flexographic presses are low cost with high productivity and efficiency.

  Press make-ready is quick.

  Flexo printing plate cylinders are removable so plates can be mounted to the cylinder off-line to accommodate production demands.

  Photopolymer plates are durable, lasting as long as several million impressions.

  There is no complex multi-component ink balancing to do, as there is with offset printing.

  Good quality print can be obtained within the first few revolutions of the printing cylinder.

  Many flexo presses are equipped with in-line finishing capabilities such as coating, laminating, slitting and diecutting, which increases productivity.

  Disadvantages of flexography

  The text/image must be reversed, so flexography is not suitable for detailed images like photos.

  Flexography produces poor shadows.

  The impressions per plate are more limited than offset.

  As each press is not the same, work done on the prepress has to be fingerprinted for the individual press.

  There is a problem with bleeding, whereas some flexo ink pigments begin to move to the substrate. There may be haloing (a line that surrounds a printed image).

  Pinholing is a problem as small holes can appear on the printed image.

  trate and anilox roll. Overall, flexographic printing quality lacks fine color detail and vibrance that is seen mostly in the final products (Warren, 1998). Therefore, examining the relative advantages and disadvantages associated with flexo can determine whether or not the students will accept it as part of their major course load and register to take the course or courses.

  ****************************************... Take 4 pieces of tape and a piece of yarn, then measure the distance out on your wall. Make the frame by taping the yarn in four corners of the frame. Step back and see if its what you are hoping for. You could use 4 needles in four corners too. Then string the yarn/string around them to make your frame. Measuring your frame as a television is measured puts your poster at something like a 65" screen if that helps. Lining about 25 sheets of standard printer paper works out to 5 sheets wide by 4.5 sheets long approximately. Tape them up on your wall to get a feel for your poster. You could use a towel or two measured out to the sizes you need and pin them up. A sheet could be folded and paper clipped to the dimensions you need and pin it up. Hope one of these will help. Good luck. **************************************...
