What are these press marks on a medicine label?

Hi!

I received these labels from another company. I must edit them lightly, and then send them to press.

They have these marks on the sides (see picture below) and I don't know what they mean.

They are sticker labels for bottles that will contain veterinary medicines.

Any help is higly appreciated! Thanks!

They look like volume markers.

Hi, would you please explain to me what are those? 
this is a 20 ML label. But on the sides it states 1/2, 1 Lt, 1 1/2. I don't see the connection

It says that you must dilute them with water (sorry my Spanish is crap! 🙂 )
So I understand it's the dose scale to make up to x liters
as in if you want to make up 1 liter 1/2 of end product, you must use 3/4 of the bottle, and only 1 quarter if you want to make up half a liter.

Does it make sense?
