Ever wondered if you are using the best ink for your needs and your Print Shop, but really wasn’t sure what the difference between Waterbased and Plastisol was? Dave Roper MD of Screen Print World has compiled a list of the pros and cons for both forms of ink, how mesh count will affect your print, Squeegee angles and other handy tips and tricks of the trade.

Waterbased ink is different from plastisol in exactly the way you might expect; Plastisol does not use water as a solvent, while waterbased ink does. Once printed, this kind of ink needs to evaporate in order for the ink to cure. Waterbased ink can either cure at room temperature over time, or by running the garment through a dryer at 160°c and usually needs at least 1 minute.

Plastisol ink is a PVC based system which doesn’t use a water solvent. It’s a thermoplastic ink, meaning it has to be heated to a high enough temperature to cause the molecules of PVC resin and plasticizer to cure. The temperature at which plastisol usually cures on textile is 160°c.




We have put together two simple charts to really help you make the decision on which type of ink would make the ideal match for your print job.

  • 24t- Beach Towels, Glitter inks, Thick Inks.
  • 43t- Textile inks, Opaque inks, T-shirts.
  • 55t- Textile inks, Finer textile designs, waterbased.
  • 62t- Enamel inks, Very fine textile ink
  • 77t- Paper and board inks.
  • 90t- Vinyl inks, Paper and board inks, Plastic ink.
  • 120t- Halftone printing, Paper and board inks.
  • 150t-UV Printing, Very fine halftone work, Usually graphic.

 

Confused about Mesh count? We have you covered! This is Dave Ropers list of the Mesh counts that generally should be used for each different job types.

 

 

Lets talk Squeegee angle, pressure and off contact!

When printing with plastisol inks you will need a higher off contact in order to lay the ink on top of the garment. When printing with waterbased inks a lower off contact is needed to double print and drive the ink into the garment. For more information on squeegees you can read our blog dedicated to them here 

Waterbased Ink.

  • Heavily flood the screen!
  • Keep a trigger spray bottle handy and fill this with water. You can use this to keep the ink wet for printing.

Plastisol Ink.

  • Leave the screen printed-not flooded.
  • Do not use white spirit or screen wash as thinners/reducers. Always use curable reducer.

Are you thinking about introducing folding and bagging  garments into your printshop? Dave Roper our CEO and screen printing expert, explains why now is the right time to introduce this into your screen printing process.

Why  do I need to fold & bag?

Its an extra service you can offer your customer, maybe some of your competitors don’t offer this as a service and this might give you the edge against them in a competitive world. You can also earn extra revenue from offering this service, lets break this down into number of garments being folded a day and what is the best route to go.

50-250 Garments a day.

Will usually be done by hand or maybe using a T-shirt folder, which will give you a nice even fold each time. Then it as simple as popping the garment in a plastic bag, job done.

250-1000 Garments a day.

1000 garments by hand will take a while but depending on how much you charge, it could be worth looking at a semi automatic folder. Semi auto folders like the FX23 you pop the garment on & it folds a shirt in 6/8 seconds, you can then drop a bag on it.

You will need a small compressor for this type of machine but its very easy to use. A machine like this will cost in the region of 10k for a new one.

1000 plus garments a day.

With this many garment I would 100% look at a full auto line as it could take up to 10 staff to fold 1800 garments in a hour which is what a Amscomatic K950 with an auto bagger could fold in one hour.

The investment with a bagger could be 50k, it will fold, bag and label the bag all with one person on the machine….. Just think 10 staff could cost a lot more, plus the K950 never calls in sick on a Monday!

The most popular glue on the market is in aerosol cans, lets look at the positives and negatives of running this type of system in your shop.

Positives

  • They are quick and easy to use.

Negatives 

  • They are expensive to buy.
  • They release chemicals into the atmosphere.
  • They make your working environment uncomfortable to work in.
  • They will knock years of your press, by plastering it in glue and fluff.
  • They are dangerous to work with due to them being flammable.
  • You have to dispose of them correctly so will cost you more.
  • The nozzles clog easily.

So what are the alternative to this flawed method of gluing a pallet?

You can buy a waterbased glue like Tekmar TB HV Waterbased Pallet Adhesive which has the following advantage over the aerosol cans:

  • Its cheaper.
  • Easier to apply and use.
  • Its better for your lungs.
  • Kinder to the environment.
  • Will not age your press by 10 years.

If you want to make it easier to apply the waterbased glue then invest in the Tekmar TB500 or TB1000 adhesive system. This will  make the product even easier to use with all of the benefits of waterbased glue.

An alternative to this is a pre glued pallet mask/paper such as the PMI Dual tack pallet mask. This is a 2 in 1 method of protecting your pallets and gluing them at the same time a win, win! The bottom line Kick the cans!!
