+===== Screen Printing - Negative Method =====
+This section gives step-by-step instructions along with photos to screen print DASL logo in a negative method.
+Negative method is blocking the parts of the screen and printing the parts that is not blocked.
+This way is easier and you can save time than using all of the materials in the kit.

 \\
-**Step 1**
+{{:jihyun:스5.png?200|}}{{:jihyun:스5.jpg?200|}}{{:jihyun:스6.jpg?200|}}
 \\
+It includes lots of things but for negative method you will need paint, mesh, squeegee from the kit.
 \\
-<Add photos to make step easier to understand>
+{{:jihyun:스7.jpg?300|}}
 \\
+. Fabric to print.
 \\
-**Step 2**
+{{:jihyun:스8.jpg?300|}}
 \\
+. Tape that is water proof due to using paint.
 \\
-<Additional steps like **Step 3**, **Step 4**, etc>
+. Cutter and a sheet of paper.
 \\
-==== Programming ====
+\\
+**Step 2 : Screen printing**
-A link to the source code can be found <provide URL to your code, probably saved in this DASL Wiki>.
 \\
-The goal of the code is <brief explanation>.  It works in the following way
 \\
-----
+{{:jihyun:스9.jpg?200|}}
-<!- Insert a snippet of your code here.  Try to keep to less than 0.5 page long -->
+\\
-----
+. Draw(recommend printing) a DASL logo on a sheet of the paper.
+\\
+{{:jihyun:스10.jpg?300|}}
+\\
+. Cut out the logo with the cutter. At this point, the part that is cut out is going to be printed. Make sure to reduce mistakes in order to print the logo neat.
+\\
+{{:jihyun:스11.jpg?300|}}
+\\
+. In order to use mesh, this is upper part. This part is going to be used to spread the paint. So you should put paper and tape underneath it.
+\\
+{{:jihyun:스12.jpg?300|}}
+\\
+. So flip it over and tape the paper you've cut. The logo should be flipped over too. And when you tape the paper check it is waterproof and be careful not to block the logo.
+\\
+{{:jihyun:스13.jpg?300|}}
+\\
+. After taping it you are ready to do screen printing. As you can see in the picture, put the mesh on the fabric.
+\\
+{{:jihyun:스14.jpg?300|}}
+\\
+. Spread the speedball fabric paint.The paint is going to go through the part that is cut out and print the logo.
+\\
+{{:jihyun:스15.jpg?300|}}
+\\
+. Use the squeegee to spread the paint with the light pressure. You can use any direction you want. Just make sure paint is spread evenly and fully covered the logo . Be careful not to spread the paint through out the paper you taped.
+\\
+If you want to prevent from making a mistake when you spread the paint there are two ways :
+\\
+Not to use too much paint.
+\\
+Use more papers to cover all of the part of the mesh you are not going to print.
+\\
+{{:jihyun:스16.jpg?200|}}
+{{:jihyun:스17.jpg?200|}}
+\\
+. This is the picture of the paint that is spreaded evenly and shallow.
+\\
+{{:jihyun:스18.jpg?300|}}
+\\
+. Carefully detach the mesh from the fabric and you're logo will be printed.
+\\
+{{:jihyun:스19.jpg?300|}}
+\\
+. You can print continuously.
+\\
+. After printing wash the mesh and squeegee before the paint dries.
+===== Failures and success of screen printing =====
+\\
+There are some conditions that you might fail during the screen printing. If you keep in mind followings below you will be able to screen print professionally.
+\\
+\\
+**- While screen printing -**
+\\
+\\
+{{::스20.png?300|}}
+\\
+. Don't change the location after spreading the paint.
+\\
+You will not be able to use the paper again. If you use that paper again it will cause smudges like the picture.
+\\
+\\
+{{:jihyun:스21.jpg?300|}}
+\\
+. Put the fabric on the flat place. And check there is no wrinkles. Or it will look like the picture.
+\\
+\\
+{{:jihyun:tm22.png?300|}}
+\\
+. Do not spread the paint too wide from the logo. You will accidentally stick out the paint like the picture.
+\\
+. Also use the proper amount of paint to spread evenly. You can see in the picture that the some parts are not painted completely.
+\\
+\\
+{{:jihyun:스24.jpg?300|}}
+\\
+. So far it is said not to use the paint too little, do not use it too much as well. Paints tenacity is high so when you put too much paint and remove the mesh, paint will stretch and be every where.

-This tutorial's objective was to <fill in the blank>. Complete <choose: construction details, source code and program descriptions> for <fill in the blank>. Once the concepts were conveyed the reader could <fill in the blank>.
 \\
 \\
-Speculating future work derived from this tutorial, includes <fill in the blank>. In the big picture, the problem of <fill in the blank> can be solved with this tutorial.
+{{:jihyun:스25.jpg?300|}}
+\\
+{{:jihyun:스26.jpg?300|}}
+\\
+. Use the material that can absorb paint like the first picture.
+\\
+Use the material that is flat.
+\\
+\\
+. If you use the material that cannot absorb the paint it will be like the second picture.
+\\
+If you don't use the material that is not flat it will be like the second picture.
+==== Final Words ====
+This tutorial's objective was to teach the students how to do screen printing in negative method.
