What are the best tools or methods to change colors in a PDF for specific printing needs?

Does anyone know how to modify the colors in a PDF document? I’m looking for ways to make adjustments, like replacing black text with colored text or changing the background color, for better printing results. What software or online tools do you recommend?

There are many online tools available to modify colors in PDF documents. Based on my experience, SuperTool is an excellent choice for replacing black text with colored text, as it offers a straightforward interface and powerful editing options. Other tools like Adobe Acrobat and small PDF editors also work well for adjusting text color or changing backgrounds. These tools are efficient for improving print quality, especially when trying to avoid excessive black ink. Also, your choice of tool may depend on your budget—what kind of budget are you working with for this task?
