Compression Used: Photoshop and Illustrator

Now I have completed both my DVD Inlay and my DVD label, I am now going to be thinking about exporting my designs. This is why I did the experiment within the previous post. This will then be able to tell me which file type is best not just for the size but also the quality for my design.

Photoshop Compression

After have a good look at the results I am pretty certain that I will be compressing/exporting my file as a JPEG. This is because this seem to have the best results for when it came to quality unlike GIF where it had the file size large but lost a lot of its quality. Also with the other file types such a BMP and PNG the quality is there but it takes up a lot of file space, which does not really help. Especially if I was going to take my design to a special printers and they have to open the design it would then most likely lag because it would take longer to open due to the file size.

So, I have had a look at the JPEG options which I have listed and tested. I eventually choose to save the file at 100% and at a 12 quality rate. I know within the testing that the file is quite big, however, I felt that this was appropriate for my design because there are little bits of detail such as the splatters which I still wanted to keep at a higher quality.

So, to do this you go to File > Save as. You then locate where you wish to save the file. Before you click save, there is a little scroll down menu before where you enter the name of the document. Here you click on the little arrow and lots of different file types will appear in a list. I then selected JPEG and then clicked save.

This will then bring up a menu in Photoshop. This menu allows you to change certain items when saving the item. The only item I am interested in, in this menu which is the Image Options. Here I am able to change the quality of the image, this also shows how big on average the file will be depending on the quality. In this case I want it on the highest setting meaning that the file size will be large. After setting the image option I then clicked OK and the file has been saved and compressed.

Illustrator Compression

After have a good look at the results I am pretty certain that I will be compressing/exporting my file as a JPEG again. This is because this seem to have the best results for when it came to quality unlike GIF where lots of the quality has been lost no matter what setting you place it on. Also with the other file types such a BMP and PNG the quality is still not as great as the JPEG, even thought it is better they are better than the GIF. So, this is the reason why I have chosen JPEG again.

So, I have had a look at the JPEG options which I have listed and tested. I eventually choose to save the file at 300 resolution and at a 10 quality rate. I know within the testing that the file is quite big, however, I felt that this was appropriate for my design because there are little bits of detail such as the splatters which I still wanted to keep at a higher quality.

However, I have some reason forgot how I actually saved the via Illustrator. So, I am going to be doing it via Photoshop. I will again be using the same settings which I have used for the DVD Inlay. Again, I used this setting again because I felt this was the best one for my design due to the smaller details, which this setting I feel will keep this detail at a good resolution. So, I followed the same procedures for the inlay for the label.
