"You can usually print at least 180 shirts per hour and because the Trooper is an automatic press, you can print 180 - 6 colour shirts an hour. An average price for a 1 colour print on a 100% cotton t-shirt ranges from $5.50 to $9.00 depending on the number of shirts in the order and you charge much more for a 6 colour shirt. An order for 72 shirts would take less than 25 minutes to print and you would charge at least $8.00 per shirt for 6 colours or $576.00.


$144.00 72 shirts would cost about $2.00 each when you buy in dozens. $ 21.00 Screen making materials average about 3.50 per screen. $ 3.60 Calculate ink cost at $.05 per shirt $ 1.00 Lights and electricity $169.60 Total cost of materials.


It will also take you about an hour to make a screen, and only a little longer to make more screens.


You charge $576.00 minus the materials cost ($169.60) and you pay yourself $402.40 for a job that takes less than 2 hours to produce.  One job like this per day and you're making $100,000+ a year." - http://www.lawsonsp.com/technical-support/support-articles/259-business-information/420-how-to-start-a-screen-printing-business

    A Platen press is made up of two surfaces called the bed and the platen. The platen provides a smooth backing for the paper or surface to be printed on. The plate ( the image that is going to be printed) is locked into place on a flat surface. The plate is inked and placed on top of the substrate until the ink is printed onto it until it is taken off to reveal the print.

    Rotary letterpressing comes in two types - sheet-feed and web-feed. Web-feed rotary presses are the most popular type for letter printing and are often used for printing newspapers. 

    Flat-bed cylinder letterpresses use either vertical or horozontal beds. The plate is locked into a bed which passes over an inking roller and then against the substrate.]]>     2016-09-06 12:47:40 UTC https://padlet.com/jhoward1875/fo7tstd76zbb/wish/121755545     jhoward1875 https://padlet.com/jhoward1875/fo7tstd76zbb/wish/121756258 2016-09-06 12:49:49 UTC https://padlet.com/jhoward1875/fo7tstd76zbb/wish/121756258 jhoward1875 https://padlet.com/jhoward1875/fo7tstd76zbb/wish/121757055 2016-09-06 12:52:01 UTC https://padlet.com/jhoward1875/fo7tstd76zbb/wish/121757055 jhoward1875 https://padlet.com/jhoward1875/fo7tstd76zbb/wish/121757552 2016-09-06 12:53:08 UTC https://padlet.com/jhoward1875/fo7tstd76zbb/wish/121757552 Quality, effort and price jhoward1875 https://padlet.com/jhoward1875/fo7tstd76zbb/wish/121758240 Letterpress printing is a lot more expensive than modern standard printing as it takes a lot more effort. For example, I found prices for letterpress business cards for £120 for 250 of them which is a substantial amount more than standard ones. This tells us a lot about the quality too as people are willing to pay a lot more money to get this style of print because the quality is a lot better than a standard print. It is also because it takes more time to make it as you have to physically make the bed that is being printing onto it which can often be difficult as you need to make it in reverse for it to print properly.]]> 2016-09-06 12:54:40 UTC https://padlet.com/jhoward1875/fo7tstd76zbb/wish/121758240 Uses jhoward1875 https://padlet.com/jhoward1875/fo7tstd76zbb/wish/121758796 This form of printing is often used if a company wants a quality stylish look to their product and it is often used on wedding invitations and business cards as stated previously.]]> 2016-09-06 12:55:54 UTC https://padlet.com/jhoward1875/fo7tstd76zbb/wish/121758796 Gravure - Overview jhoward1875 https://padlet.com/jhoward1875/fo7tstd76zbb/wish/121761031 A Gravure is a method of transferring an image onto a printing substrate.

However, the artists of Taller de Gráfica Popular, a printmaking workshop founded in Mexico City in 1937 made the process effective and used it in their graphic posters.

Also, in the production process, there are set grid lines to make the process a lot easier and make the layout have preset spacing placed in the document]]> 2016-09-07 12:37:16 UTC https://padlet.com/jhoward1875/fo7tstd76zbb/wish/122074387 Advantages jhoward1875 https://padlet.com/jhoward1875/fo7tstd76zbb/wish/122079122
  • Cost; as the business don't need to hire professional printing companies to typeset each production
  • Efficiency; The final document can be previewed and changed immediately on the companies own software.

  • Expense; any and all additional software and hardware needs to be bought to start desktop publishing, for instance, you'll need a computer that can run the software and the software itself, with the software often costing more than the hardware itself
  • Training; Any and all staff that the company want to make new documents have to be trained to use the software efficiently and will need to spend time training and picking up the skills

This can be used to produce copies of all kinds of written works, printed and graphic. The basic process is photoconductivity, an increase in the ability of certain substances to allows an electric current to flow through them when struck by light.
    "Xerography typically uses an aluminium drum coated with a layer of selenium. The light passed through the document to be copied, or reflected from its surface, reaches the selenium surface, onto which negatively charged particles of ink (i.e., the toner) are sprayed, forming an image of the document on the drum. A sheet of copy paper is passed close to the drum, and a positive electric charge under the sheet attracts the negatively charged ink particles, resulting in the transfer of the image to the copy paper. Heat is then momentarily applied to fuse the ink particles to the paper." - Encyclopaedia Britannica - Photocopying machine]]>     2016-09-07 13:21:13 UTC https://padlet.com/jhoward1875/fo7tstd76zbb/wish/122092107     Advantages jhoward1875 https://padlet.com/jhoward1875/fo7tstd76zbb/wish/122095927
