As we know Acrobat provides two basic types of editing.
1. Text Editing: In Text editing we edit the texts present in a PDF as text.
2. Object Editing: In object editing we resize, move a object.
Note: We can resize few characters by selecting them as objects. As by selecting those, a rectangle will be formed around the objects.We can resize the rectangle to get the desired character/s size.
The problem is sometimes we need the fonts which are generally not available in Acrobat. So we install new fonts, Generate a document either in MS Office or Open Office then convert it to the PDF to show the font.But if we want to do some text editing in the already generated PDF, then the editing font is not available in the Acrobat, instead a substitute font is used for editing which leads to font issues in many documents or forms.
Solution: By the combination of Text editing and Object editing we can easily get over this problem.
Download and install a font from a trusted source which is readily not available in Acrobat. eg: ArialMT.
Create a document either in MS Office or Open Office by selecting the required font (ArialMT) for those sections which need to be edited in the previously existing PDF. (You can directly copy the desired contents by selecting Text Editing in the existing PDF)
Convert the word doc to PDF.
Select object editing and select all those sections/text which needs to be edited (in the original PDF) in the later PDF.
Copy those contents from the later PDF.
Select object editing in the earlier existing PDF.
Select those sections/fonts which need to be edited and simply paste those contents which are copied from the later PDF.
NOTE: There is no hard and fast rule to select some sections in a PDF. In case of difficulty we may use Ctrl+Shift to select those section.
