If what is being required is a certified copy of the original results, a workaround might be to print the provided soft copy high quality (preferably colored laser) in a high quality paper (substance 100 and up) and make a colored photocopy to be used for the certified true copy.
The common misconception is the use of the term "notarized" because technically (though I am not a lawyer) in the Philippines, when you ask for something to be notarized it is entered into the notarial records of the notary public and he/she might be asked to appear in court to submit documentary proof of such undetaking should the need arise.
However, certifying a document as "true copy" is of a lesser degree than "notarized" because it simply implies that a document was presented and this signed copy is a reproduction of such document.
For all intents and purposes, a notary, can never really ascertain that the document presented is an original and truthful document because only the issuing authority, which in this case is the PTE can do that.
For all my "certified" documents submitted to AHPRA and Home Affairs, what I did was to put the following text instead of relying on the "Certified True Copy" stamp mark of the notary:...
<b class="Bold">I have sighted the original and
certify this to be a TRUE COPY
of the original as presented.</b>
Then at the bottom or at the side, a space for the signature and details of the notary public.
I think that would suffice for your needs, afterall, the CO/Registration Officer will still be verifying your PTE results using their online access.
