About Merging One Texture with Another Texture which has Transparent Background First of all, i want to explain what i am on. 
To test, i prepared a box with a material (picture 1) and a text with transparent background(picture 2) using nodes. 

Picture1, the box



Picture2 and 3, alpha/opacity map to create text with transparent background and node setting for it





Question: Is there any node option to add text texture on box's burlap texture without affecting it...like in photoshop: text layer on another layer.
Question: i was tryig it with MixRGB node but all options on it changes the textures as in picture 4. Then i wanted to render it to see what it looks like. But then text doesn't seem in rendered window as in picture 5. Why does that happen ?


Picture 4, when i try it with MixRGB node and node settings for it:



Picture 5, Text doesn't appear in rendered window:
Plug the Alpha socket in the image node into the Mix Factor of the Mix Node there instead of the Color socket.
