Laundry Printing Press Amalgamation

Here is a wacky idea, what if we could wash our clothes in a printing press?

This idea might not make much sense to a lot of people, in fact it will only make sense to only a select few those who are the intersection of the following two pies - one those understand how offset printing presses work and two those who understand how detergents work while washing clothes.

I am not sure that I am in that intersection, but its an idea i have lets see what it is-

First let me explain what i believe happens in an offset printing press made of different kinds of rollers. n one roller is the paper and the other roller has the image carrier. These two must roll over each other to transfer the image from the image carrier to the paper (substrate).

Now how does this image transfer take place?
The image carrier has two areas , one carries the image and the other is blank. The area that carries the image is oleophilic (it attracts oils), the area that is blank is hydrophillic(it attracts water). The roller with the image carrier goes into a bath of ink which is oil based so it sticks to the area on the image carrier which is oleophilic. Now to get rid of any excess ink it goes through (I believe I am not sure) either a water bath and/or gets scraped by a blade. Now that the optimal amount of ink is on the carrier it is rolled over the substrate(Paper) to transfer the image (print).

Enough of that i am pretty sure I got some things wrong over there, but the basics are I believe correct. I will do some research and come back and correct it later.

Now about washing dirty linen. Washing is done with the help of water, detergent and of course our dirty laundry. The magic component are the detergent molecules. These molecules consist of two parts one is oleophilic and the other is hydrophilic. Now the dirt in the dirty laundry is supposed to be oil based so it sticks to the oleophilic part of the detergent molecule and the other half of the detergent molecule is hydrophilic so it sticks to water.

Now we have a tug of war between the dirt stuck to our dirty laundry the oleophilc half of the detergent molecule stuck to the dirt and the hydrophilic half of the detergent molecule stuck to the water. Now it is up to the washing machine to pull of this great tug of war of the dirty laundry and make it clean laundry.

Thats the similarity between printing and washing. Next we will try and find out how we can marry the two together in a meaningful relationship.
